“A Tale of Two Springfields” is the second episode of Season 12 and is the 250th episode of the series overall in both broadcast and production order. The episode was written by John Swartzwelder and directed by Shaun Cashman and guest starred The Who. The episode was inspired by Don Payne based on Don’s mom area where one side would spread rumors of the other side. Larry Doyle then pitched it to have the both sides divide, because of area code. The episode features cultural references to The Who and Freedom of Speech and has also received positive reviews from critics.
In the episode, while calling Animal Control over a badger taking residence in Santa’s Little Helper’s doghouse, Homer discovers that Springfield has two different area codes—and ends up leading a revolt that splits the town in two.
