Trivia: Another gag that makes the location of Springfield more ambiguous. In one episode the superintendent of the Springfield school systems says "This school used to be the worst in the state of Missouri." Everyone gives him a shocked look, and then he adds "which was why it was moved brick by brick to its present location."
Trivia: Matt Growning did all his animation in black and white and another animator was in charge of coloring. When she chose yellow, Matt said it worked and liked it (consequently when she chose purple for trees they rejected it.) The idea behind the yellow after that is so when you're flipping through the channels and come across yellow animated characters, you'll know right away it's The Simpsons.Tobin OReilly
Trivia: Hank Azaria, voice for many of the characters on the Simpsons, said in an interview with Conan O'Brien that most of his voices were just bad celebrity impressions. Moe Syzlak is Al Pacino, Louie the cop is Sylvester Stalone, and Comic Book Guy is someone he went to college with who had a personality much like comic book guys. With other characters who Azaria doesn't do are also celebrity impressions. For example, Mayor Quimby is JFK.
Trivia: In New Zealand when the show was being shown on the TV2 network, the Itchy & Scratchy cartoons over a period of time were continually edited to try and remove as much violent content from them as possible. However around 2000-2001 the network edited out every single Itchy & Scratchy cartoon making the cartoon almost non-existent in the show despite some of the cartoon's content not being as objectionable as the rest.Lummie
Trivia: Creator Matt Groening holds the world record for the most DVD commentaries by one person. In total he has done over 100 commentaries over the first five seasons on DVD. The only episodes from seasons 1-5 he has not commented on are "Call of the Simpsons", "The Telltale Head", "The Crepes of Wrath" (all season one), "Homer and Apu" and "Secrets of a Successful Marriage" (both season five).
Trivia: The Simpsons has a joke that has been run many times in different forms. They make a reference to the movie "Ben Hur", a movie about a Roman Gladiator. It has a famous chariot scene where one of his opponents has a chariot with spikes on the wheels. He uses it to cut up his opponents wheels and make them crash. This joke is frequently used in the show. It can be seen in the episode where they go to New York, where Bart makes a Soap Box racer, and many others.
