1.1. What's the show supposed to be about?
Hey Arnold! is supposed to be about "life in the big city as seen through the eyes of a nine-year old boy with a football-shaped head". (Originally, "and a vivid imagination" was added to the end of that, and at the beginning of some first-season episodes - for example, "Downtown as Fruits" and "24 Hours to Live" - you see Arnold daydreaming; however, that doesn't happen nearly as much now.)

1.2. What's the history of the character Arnold?
Back in 1986 or so, animator Craig Bartlett (who also did the first set of "Penny" cartoons (a girl with actual pennies for eyes) for
Pee-Wee's Playhouse) developed the character "Arnold", a young boy usually dressed in a school uniform, complete with little hat (this is why Arnold has a hat on the show), who was always daydreaming, whether in church, in school, or just watching TV - and his daydreams were quite vivid. (When a preacher read Psalm 23, Arnold visualized it literally; when his school band played "The Skaters Waltz", Arnold daydreamed he was a figure skater.)
In 1991, "Arnold" became a comic strip in the short-lived "Simpsons Illustrated" magazine. (It didn't hurt any that Craig is married to one of the sisters of The Simpsons creator Matt Groening.) A few years later, Nickelodeon was looking for some new ideas for animated shows, and asked to see Craig's work. When they saw Arnold, they said that they wanted a show based on him. The pilot episode (an early version of "24 Hours to Live", with a few differences, such as Arnold wearing an orange sweater and a blue shirt) was shown in movie theaters along with Nickelodeon's first movie, "Harriet the Spy". On October 7, 1996, the show debuted on television. (It was the first show to air on Nickelodeon (as opposed to Nick At Nite) at 8:00 on a weeknight.)
(The answers to your next three questions are:
(1) Craig's wife's name is Lisa (Lisa's younger sister Maggie is involved with some of the Hey Arnold! "chapter books");
(2) Yes, she is the person whom Lisa Simpson is named after;
(3) No, she doesn't really play the saxophone.)

1.3. When is the show on?
The schedule changes so much that this is hard to answer accurately.  The schedule chart on the home page of this website has the schedule for the next two weeks or so, although Nickelodeon can (and has) change the schedule at the last minute.

1.4. Why do they keep replacing it with another show?
There was a time when this question was "Why do they keep replacing it with Rugrats?".  However, sometime in 2001, SpongeBob SquarePants replaced Rugrats as Nickelodeon's most popular show (in part because it has a large following in universities for some reason).  Anyway, back when Rugrats was popular, Nickelodeon liked to replace airings of its other shows with Rugrats marathons, sometimes on very short notice; what was supposed to be the first airing in the USA of "Grandpa's Packard / Phoebe's Little Problem" was replaced with a Rugrats episode.  However, there doesn't seem to be as much of this happening with SpongeBob.
Anyway, it's usually for one of two reasons; either Nickelodeon thinks another show would get better ratings, or there's a show (usually a newer one) Nickelodeon wants to get people to watch.


2.1. What's Arnold's last name?
"Shortman (pronounced "SHORT-min"). It is revealed in The Jungle Movie.

2.2. What is that orange thing Arnold wears around his waist?
You don't recognize the kilt of the Clan MacArnold? Well, that's because there's no such thing -
what? I didn't what? Oh...

2.1.1. Really, what is Arnold's last name?
You are not alone in asking this; it's probably the most-asked question Nickelodeon gets (especially now that the other "really asked question", "What happened to Chuckie's first mom on
Rugrats?", has been answered).
Arnold doesn't have a last name yet (despite what he said on one of the "Cafeteria Confessions" - it's like when they're about to tell you exactly where "Springfield" is on
The Simpsons, only for something to happen and you don't find out). Craig Bartlett said that he might give him a last name, but it's not definite. (Note that Rocko on Rocko's Modern Life never had his last name revealed either (although according to Joe Murray's original design of the character, his name is "Rocko Rama"), even though just about every other character's last name was mentioned.)
I know what it's not; it's not "Vineland".  Somebody misread the label on the package with the telescope in it in "Sally's Comet", which said "Arnold, 4040 Vineland".  At the time, 4040 Vineland was the Sunset Arms address; later, it would be 4040 Vine Street.  (4040 Vineland Avenue in Studio City, CA is the location of the original Nickelodeon Animation studio, before they moved to the new Burbank studio.)
(Oh, and I know about the episode of
The Simpsons where they say "northern Kentucky" - but did you know that there is a version of that episode where they said "southern Missouri"?)

2.2.1. Really, what is that orange thing Arnold wears around his waist?
In "Cool Party", Rhonda asks Arnold this question - and Arnold removes his blue sweater to reveal his orange shirt, which isn't tucked into his pants and usually sticks out from underneath the sweater. (Then again, the way Grandpa quickly takes to golf in "Grudge Match", maybe there's some Scottish blood in Arnold after all...)

2.3. Why does Arnold live with his grandparents? Where are his parents?
The story is explained in "Parents Day" and "The Journal"; the short version is, Arnold's father is a doctor who visits out-of-the-way parts of the world (Flying Doctors/Voladores, Medicines sans Fronteirs/Doctors Without Borders, that sort of thing). His co-worker considers him a "ladies' man", but he figures that no woman would ever put up with the amount of travel he does...until he meets one that travels just as much; an archeologist. It's love at first sight; they get married, have a son (Arnold), and settle down. At least, until Arnold's father's friend asks him to perform another mission; despite his protests that he has a wife and son, he gives in, and Arnold's mother joins him. Leaving Arnold with his parents, they take off in their two-seater biplane...and haven't been heard from since.
(By the way, for those of you outside of North America, Mother's Day is the second Sunday in May here. For those of you in North America, the UK celebrates "Mothering Sunday" in March.  Father's Day is the third Sunday in June pretty much everywhere in the world, but that's another matter.)

2.4. Where do you find out what the new episodes are going to be - and why are they wrong sometimes?
Nickelodeon sends what they think they are going to show two weeks in advance to the online TV listings companies.  Nick.com seems to be the most accurate, but it does tend to change with only one or two days' notice.

2.5. What merchandise is available?  What about DVDs?
"Not much", and as Nickelodeon feels there are shows that sell merchandise better (most stuff is bought by really young kids), don't expect much more any time soon (except for movie-related items).
There are five video tapes, four of which have about 1 1/4 hours' worth of the show, and the fifth ("Arnold's Christmas") about 45 minutes' worth.  Other than for some "Nicksclusives" on the first two tapes ("Urban Adventures" and "The Helga Stories") that haven't aired in years, they don't have anything you haven't seen over and over again.
There are a couple of CDs with some of the songs on them, "The Best of Nicktoons" and "The Newest Nicktoons".  The first one has long been out of print (it's also the only CD with Ren & Stimpy songs), but the second one should still be available online, and possibly in music stores (in the children's music section).
There is a "Nickelodeon online store" at http://shop.nickjr.com that has some merchandise.
Also, from December, 1997 to January, 1999, there were a number of Nickelodeon stores in malls throughout the country (like the Disney and Warner Brothers stores). Although most stores concentrated on
Rugrats and Blue's Clues, the three large stores - one at the Great Mall of America in Minnesota, one just outside of Chicago, and one just outside of New York City - had larger selections for the other Nicktoons (as well as "Nick At Nite"-based stuff). (For whatever reason, there was no merchandising of the "live-action" shows, except for the occasional T-shirt.) Supposedly, the original intent of the stores was to see which items were popular, so they could be marketed in larger chain stores (like, say, K-Mart) nationwide. Most of the Hey Arnold! stuff (besides the videos and the dolls - and there weren't any Helga dolls to begin with) was small plastic items, like curly straws with characters on them and plastic characters that fit on pencils. (Only Arnold and Gerald were available; I can only assume that Helga's hair would have been considered a sharp-edge hazard of some sort.) The smaller stores also had T-shirts and hats (the hats just had the show's logo). The large stores had other items at various times; for example, a plastic yellow heart-shaped locket with Arnold's picture in it, or a picture frame with Helga in one corner.
In late 1998, Viacom (the company that owns Nickelodeon) decided that it didn't want to be in the retail store business, so all of the Nickelodeon stores, as well as the main Viacom store in downtown Chicago (which, among other things, sold a lot of "Star Trek" stuff - and probably the only place in the world to get
Duckman stuff, if you're familiar with that show), closed in January, 1999. (Although the closings were announced months in advance, no exact date was given, so it came as quite a surprise to some of the stores' employees when they showed up for work on February 1 and discovered they - and their bosses - were out of jobs.)
(Warner Brothers did something similar with its stores in 2001.)
(No, I don't know what happened to the existing stuff. It could be in a landfill somewhere. Between you and me, that's pretty much where the Arnold pencil topper belongs; unlike most of the others, Arnold had to be put on top of the pencil, over the eraser, and it kept falling off.)
Back issues of Simpsons Illustrated, which contain the Arnold comic strips, are hard to come by. You can try searching eBay, but be prepared to pay a lot (and remember that there is a web site that has all ten of the comic strips on it).
Two of the original Arnold claymation shorts are available on the International Tournee of Animation video series; #3 has "Arnold Escapes from Church" and #4 has "The Arnold Waltz".  www.amazon.com and www.reel.com may have these tapes available; the last time I looked, each tape cost about $20.
Nickelodeon has released a number of "chapter books" for some of its shows; they sell for about $4 each.  (A chapter book version of the movie sells for $5.)
There are no DVDs, except for the movie; in fact, until early 2002, there were no Nickelodeon DVDs at all, other than the two Rugrats movies.  Only Nickelodeon's currently popular shows are on DVDs, except for the Christmas and Halloween DVDs, which contain episodes from different shows.

2.6. What other shows have the actors done?
The list is too long to include here - and even if I tried, it would be quickly out of date. There are two sources I use to find out things like this.
First, the Internet Movie Database (
us.imdb.com in the USA; in other countries, www.imdb.com will point you to a "local" copy), which includes the cast lists for a large number of movies. The only problem with it is, the information comes from volunteers and is not necessarily entirely accurate. (For example, IMDB had a listing for an "upcoming movie version of The Simpsons" at one time, even listing a writer and director, despite the fact that everyone on the show's staff says that there's no plans for a movie as it takes all of the time they have just to do the TV series.)
The Complete Guide to Prime Time Network and Cable TV Shows - a new version has just come out at the end of 1999. (The newest version has a blue cover that includes a picture from South Park on it; the previous version has a red cover that includes a picture from Ren & Stimpy; earlier versions do not include the words "and cable" in the title.) The latest version is complete through mid-1999; it includes CatDog and The Journey of Allen Strange but not Rocket Power or The Amanda Show. (They do make one mistake in the "Hey Arnold!" listings; Rhonda's last name is listed as Willington instead of Lloyd.)
(There's also
The Encyclopedia of Daytime Television, which covers daytime shows, including Saturday morning ones, but it's not particularly accurate and the voice lists for cartoons isn't very full; besides, most Saturday morning cartoons list everybody who does a voice in any episode in every episode's cast list (Nickelodeon's episodes of Doug also do it this way), and sometimes they have to get the list ready before they've recorded every episode so some names are missing.)
However, probably the "biggest" roles by any of the kids who have done voices on the show belong to Lacey Chabert (Penny on the
Lost in Space movie, Eliza on The Wild Thornberrys, Claudia on Party of Five - and Ruth in "Arnold's Valentine" and "What's Opera, Arnold?") and Haley Joel Osment (the boy who could see dead people in The Sixth Sense, Murphy's son Avery on Murphy Brown - and Curly in "Deconstructing Arnold"), although Alex D. Linz (Arnold in "The Journal" and "April Fool's Day") is making a name for himself as well.
A number of celebrity adult actors have done voices; they fall into three categories - famous for things done years ago (for example, Rose Marie, who was Sally on The Dick Van Dyke Show and is in "Crabby Author"), famous at the time (for example, Andy Dick in "Monkeyman!"), and "before they were stars" (Ryan Seacrest was in "Fighting Families" long before he started hosting American Idol).

2.7. I liked (choose one: Toran Caudell, Phillip Van Dyke, Spencer Klein) as Arnold. Why did they replace him with (Phillip Van Dyke, Spencer Klein, Alex Linz)?
Most animated shows use adult women to do the "kids parts" (including boys). (For example, Tommy, Chuckie, and Phil on
Rugrats are voiced by women, as is Bart on The Simpsons.) This is because it is very hard for a man to do a voice that sounds like a boy, as men's voices change from high-pitched to lower-pitched, usually when they're about 13. Somewhere between the first and second season, Toran's voice changed to the point where he could no longer sound like Arnold, so they had to replace him with Phillip; two years later, the same thing happened with Phillip, so they had to replace him with Spencer.  If you don't think their voices can change that much, watch "New Bully on the Block" and tell me that you can tell that the voices of Wolfgang (Toran) and Ludwig (Phillip) were Arnold at one time.
Arnold is not the only character replaced; there have been a number of Eugenes, and Sam Gifaldi is replaced by his brother Taylor in "April Fool's Day".  Also, Hey Arnold! is not the only show that has had this problem; there have been three Sams and two Twisters on Rocket Power had to be replaced for the same reason.  (Sometimes, they will write "voice changes" into the show, presumably because they can't find anybody else who sounds like the character; Gerald's "removed tonsils" in "Gerald's Tonsils" was written to explain his voice changing.)

2.8. Will there be any more new episodes?
Right now, there are no plans to make more episodes of Hey Arnold!.  ("Phoebe's Little Problem / Grandpa's Packard", which aired on Nickelodeon in June, 2004, was the last one that Nickelodeon had not aired.)
(Then again, never say never -
Rugrats isn't the only cartoon to make new episodes years after it "stopped"; The Flintstones had a break of about ten years, and The Jetsons over twenty years (the episodes that end with George and Astro chasing a cat were made in 1962; the others are from at least 1984).)

2.9. Where does the show take place?
It's not meant to take place anywhere specific, but in "a big city, just like the one you live in (or near)".  However, some episodes have "clues in the background" that might give Arnold's city and state a name.
First, the city: in "April Fool's Day", there's a window that says "Hillwood City Hats", so I assume the city's name is "Hillwood City".  (There is also a "Hillwood City Zoological Garden" in "Monkeyman!" and "Timberly Loves Arnold", and a "Hillwood Medical Center" in "Helga on the Couch"; also, in "Stuck in a Tree", the fire department is "HFD".)
Second, the state.  They never come out and say it, but at the end of "Road Trip", Helga and Miriam are entering Washington, and as they were originally headed to South Dakota, either (a) they were headed back home, into Washington, or (b) they were still headed to South Dakota, and for some reason, went through Washington.  Only the first one makes any sense.
Actually, the city is supposed to be some combination of (a) Seattle, Washington, (b) Portland, Oregon, and (c) Brooklyn, New York.

2.10. Where are Arnold's other grandparents?
In "The Journal", when Stella names Arnold, she says, "That was my father's name"; as she said "was" instead of "is", I assume Arnold's other grandfather died before he was born (which would also explain why he wasn't at the wedding).  Other than that, there is no mention of them.

2.11. Where can I get a copy of a certain episode?
Except for the episodes on the Nickelodeon videotapes (which should still be available through Amazon.com), there is no "official" way.  Also, I don't know of any place where you can download them (mainly because nobody was interested enough in the show to (a) capture an entire episode onto their computer, (b) convert it to a format that most people can watch, and (c) upload it (which would take hours with a dialup service) - and even if they could do all that, they need a place to put the episode so it could be downloaded without anybody from Nickelodeon finding out about it and demanding that it be removed).
Your best chance is probably to ask at one of the Arnold-based message boards (I can think of three or four of them; they should have links on this site's Links page).


3.1. Who lives at the Sunset Arms?
Besides Arnold, Grandpa, and Grandma, there's Ernie Potts (the wrecking ball operator), Oskar & Suzie Kokoshka (Suzie works at a department store; Oskar works at spending Suzie's money, although he did have a paper route once), and Mr. Hyunh (who is a cook at a Mexican restaurant). In the first season, there were three other boarders: Mr. Smith (whatever he did, he liked to keep secret - he never ate with the others, and he usually kept his face hidden), Lana Vail (she's the one with reddish hair and usually wearing a business suit), and Mr. Purdy (he only appears once - and that's just his voice - in "Gerald Comes Over"; however, they were soon removed, as none of them are in "Arnold's Christmas" when Grandpa says "that's all of us". (Lana makes some "background appearances" in some episodes; for example, in "Dinner for Four", she's in the restaurant when the cockroaches get loose.)

3.2. What's this about a second movie / "The Jungle Movie"?
A few years ago, Nickelodeon decided to make its own theatrical movies. After a couple of not particularly successful films (Harriet the Spy and Good Burger), The Rugrats Movie was a major success (it was the highest-earning non-Disney animated film until Shrek was released), so Nickelodeon decided to make more theatrical movies based on its animated shows. Originally, the next movie was planned to be a Hey Arnold! movie; the original plan was for it to be "Arnold Saves the Neighborhood".  However, Nickelodeon thought that the show's planned "Nick Flick" at the time, where Arnold looks for his parents (I assume it was meant to be the show's last TV episode), would do better in theaters, so that became the planned theatrical release and "Arnold Saves the Neighborhood" a Nick Flick.  The movie takes place in a jungle somewhere, hence "The Jungle Movie".
Months passed by, and while Nickelodeon released Rugrats in Paris, the Hey Arnold! movie was still not given the go-ahead to begin production (I think somebody had a problem with the script).  It was decided, in order to get a Hey Arnold! movie out, to turn "Arnold Saves the Neighborhood" back into a theatrical movie, as the "Nick Flick" version was finished, so most of the work was already done.  (The name was changed to Hey Arnold!: The Neighborhood and then Hey Arnold!: The Movie; my guess is that they wanted to get more people unfamiliar with Arnold to watch the movie.)
Back to the "second" movie: after what were thought to be the last TV episodes were completed, Craig Bartlett made some deal with Cartoon Network for another show he was working on, "Party Wagon" (see question 3.5).  Nickelodeon wanted Craig to stay with them exclusively, and demanded Craig sign something to that effect; when Craig didn't, Nickelodeon pretty much ordered all work on the second movie stopped and locked away somewhere.
The strange thing is, after this whole "Party Wagon" incident, Nickelodeon still wanted Craig to make three episodes of Hey Arnold! (so that there would be a total of 100; originally, "Arnold Saves the Neighborhood" was meant to be split into three parts and be episodes 98, 99, and 100); episode 98 is "April Fool's Day", and episodes 99 and 100 are "The Journal (Parts 1 and 2)" (if they're shown that way, like they did on CBS once).
In the meantime, The Wild Thornberrys Movie and Rugrats Go Wild! did not do nearly as well as Nickelodeon had hoped, so the chances of another Hey Arnold! movie in theaters is incredibly slim.  (If the upcoming SpongeBob SquarePants movie does not do well, Nickelodeon may decide to get out of the animated feature film business and stick to TV "Nick Flicks".)

3.3. Whatever happened to that contest where the winner got a speaking part on the show?
Back in 1998, there was a contest involving Kraft Handi-Snacks where the winner got a speaking part on
Hey Arnold!.  Apparently, the winner was Jessica Sodd, and her part was the girl who read the opening speech to "Romeo & Juliet" in "School Play".

3.4. At the end of the fifth season, there will be 100 episodes; does this mean that other stations will start showing Hey Arnold! in reruns?
Probably not, at least not for the moment. For shows that are on network TV, there's an unwritten rule that says that it will appear in five-days-a-week reruns once it has 100 episodes. (More accurately, it's closer to 88 episodes, as shows usually run 22 episodes per season and have to run for four seasons before there are considered to be enough episodes for reruns.) However, Nickelodeon doesn't usually sell the rights to show its shows to other stations.  (Besides, the show is also on the Nicktoons channel.)

3.5. What's this "Party Wagon" thing I've heard about?
It's another show created by Craig Bartlett.  It involves a young man in the 1800s who joins a wagon train headed towards Seattle, where they think a treasure is buried.  The 90-minute first episode aired February 27, 2004.  (It won't be on Nickelodeon, as it has a lot of gun shooting and some alcohol drinking, two things that are absolutely forbidden on Nick shows.)  At first, it was going to be a series on Cartoon Network's "Adult Swim", but then they told Craig to "tone it down" so it could air along with their other shows; eventually, they decided not to make episodes after the first one.

3.6. What is "The Patakis"?  Is it going to be a new series?
There was a plan to make a "sequel" to Hey Arnold! that took place five years later, with the fourth graders in high school, and concentrating on Helga and her family (including her sister Olga, who had graduated from college and moved back in).  It was a little more "adult" than Hey Arnold!; for example, Miriam, whose alcoholism is "hinted at" but never mentioned on Hey Arnold! (mainly because they never mention alcohol on any Nicktoon - seriously, at a Big Help-A-Thon once, they deleted the words "bottle of beer" from a song), would be attending Alcoholics Anonymous meetings.  The big change: in order to make sure Helga and her family remain the focus of the show, Arnold would never appear (the story would be that he found his parents and they moved away), except that each episode would be written as Helga writing a letter to Arnold describing what had happened (sort of like how every episode of Doug is something written in his journal).
However, Nickelodeon realized that it was not a show meant for its "target audience".  There was talk of moving the show to MTV (one MTV executive asked why it wasn't "darker"), but that was rejected as well (it's possible that somebody noticed a similarity to Daria, which didn't do particularly well on MTV either).  As far as I know, there are no plans to make even a pilot episode of the show.
There is a website that is working on "fanscripts" and designs of the characters; check the Links page of this site.

3.7. What is Helga's middle name?
It's never been mentioned on the show, but Craig Bartlett says it's Geraldine.  (The name refers to Geraldine Laybourne, who was a Nickelodeon executive at one time and was one of the founders (as was Oprah Winfrey) of the Oxygen network.)
(Helga isn't the only cartoon character with an "unspoken" middle name; Bart Simpson's middle name is Jojo - at a script reading one day, Nancy Cartwright (the voice of Bart - and the new voice of Chuckie on Rugrats) asked The Simpsons creator Matt Groening what the J in "Bartholomew J. Simpson" stood for; Matt asked Nancy what she thought it stood for, Nancy said Jojo, and Matt said that's what the name would be.)

3.8.  Are there any Hey Arnold! animation cels out there?
Yes, but they're not cheap, and they're not easy to come by.  There was an "official Nickelodeon animation cel studio", Cricket Galleries in Atlanta, but they claimed never to have seen any Hey Arnold! cels, and the last time I tried to check their website, it wasn't being maintained.
Sometime during the third season, the show switched from hand-colored animation cels to computer-colored animation, which doesn't use cels, so no fourth-season or fifth-season cels, or cels for Hey Arnold!: The Movie, exist, although it's possible that "special" cels based on scenes from the movie could have been specially made to sell (Disney does this with some of its newer movies).  Pretty much every animated show has switched to "cel-less" work, mainly because it's a lot easier; one of the last holdouts was The Simpsons, but apparently they have switched as well, mainly because the overseas studios that do most of the "grunt work" have switched to computer coloring as well.
My suggestions: first check eBay, then do a web search on Google (www.google.com) for something like "Nickelodeon animation cel".

3.9.  Which characters are left-handed?
This never seemed to be important in animation until somebody noticed that Bart Simpson does everything left-handed (probably because
The Simpsons creator Matt Groening is also left-handed).
Despite the fact that there was an "The N-Files" commercial that claimed that Arnold and Helga were the only left-handers on the show, the only character who seems to be a definite left-hander is Phoebe: she cuts her food with the knife in her left hand ("Roughin' It"), she writes with her left hand ("Operation Ruthless"), and she throws left-handed ("Pigeon Guy", based on the glove on her right hand).  However, she writes with her right hand in "Pre-Teen Scream", so it must not be that important.
Helga throws left-handed in a number of episodes ("Pigeon Guy", "The Vacant Lot", "Helga's Makeover", "24 Hours To Live"), but in "The Little Pink Book" she writes right-handed (but throws spitwads left-handed).
There haven't been that many clues to indicate what hands the other characters favor, but most of the boys throw right-handed...and bat left-handed! (Pretty much everybody bats left-handed, but this may be because the animators want to show the batter's face while the ball goes from left to right.) There have been some switches: Harold has been seen batting left-handed ("The Vacant Lot") and right-handed ("Helga's Makeover"), and Arnold has baseball gloves for his left ("The Vacant Lot") and right ("The Baseball") hands.
Arnold tends to switch hands: in "The Little Pink Book", he (and Gerald and Brainy) writes right-handed; in "Tutoring Torvald", he starts the test writing with his left hand (which he also uses to write on the sidewalk), but ends writing with his right hand. (He's also shown with the chalk in his left hand in the Games Animation logo at the end of each first-season episode.)

3.10 Is there really a "P.S. 118" somewhere?
(By the way, "P.S." stands for "Public School")
A quick search of the World Wide Web shows that there is a P.S. 118 in the New York City school system; it's located in Hollis, at the east end of Queens borough in New York. Does anybody else out there know if other cities have schools with "PS numbers", and if they do, do they go as high as 118? (Please note that the schools are not numbered based on their location, so, for example, P.S. 117 is not near P.S. 118.)

3.11 Why does someone as old (and angry) as Helga wear a large pink bow in her hair?
I can only guess the real reason, but I would say it's for the same reason Arnold has a small blue hat; they both appear that way in the original claymation shorts.
As for the "story" version, again this is a guess, but I think it's because of something in "Helga on the Couch": when Helga meets Arnold for the first time, Arnold says "I like your bow".  Helga isn't about to change the one thing about her that she knows Arnold likes.

3.12 How do I contact the show's cast?  The Staff?  Craig Bartlett?  Nickelodeon?
Since the show has stopped production, it's hard to answer the first two, as they've gone on to separate projects, and most of the cast is off doing whatever it is they're usually doing.
Nickelodeon has a "viewer relations" department, if you want to make comments about the show: the phone number is 212-258-7579.  However, this is a number for all of Nickelodeon's shows, so don't expect whoever is there to be able to answer any Arnold-specific questions.
There's a "Write to Nick" page at the Nick.com website somewhere, although considering how many shows they have and how many E-mails they must get - plus, all of the E-mails go to the same place first - there's not much chance that yours will be seen by anybody involved with the show.
The show is produced at the Nickelodeon Animation Studios in Burbank:

Nickelodeon Animation Studios
231 West Olive Avenue
Burbank, CA 91502-1825
(818) 736-3000

The only address I can think of to send your fan mail to is Nickelodeon's New York headquarters:

1515 Broadway
New York, NY 10036

(This is also where you would write to, for example, ask that the second movie be made.  However, if you do write to Nickelodeon, be nice (nasty letters are tossed into the trash) and be yourself (if they think it's something that somebody else told you to write, they'll ignore it).

3.13 What are the words to (some song heard on the show)?
The original songs have their lyrics on that show's page.  (For example, the words to Dino Spumoni's song in "The Old Building" are on the page for that episode; go to the Season 1 page, then find "The Old Building" and click on the title.)
