A Tale of Two Springfields/References

Trivia

 * After Homer hears about the change of area code, the badger shows up and Homer goes "Go away! We got bigger problems now." This is a reference to the recurring sudden plot changes in most Simpson episodes.
 * This is the 250th episode of the show.
 * Area code 636 is actually assigned to suburbs of St. Louis, Missouri ; although this seems to reveal Springfield’s state, the real Springfield, Missouri is in a different area code. Area code 939 is one of two codes used in Puerto Rico.
 * This is the only episode of the Simpsons directed by Shaun Cashman.
 * When Lisa is trying to find out what badgers eat she goes on whatbadgerseat.com. A real version of the site (whose logo is reminiscent of ask.com) was made by the producers of the show.
 * At the moment when Homer is introduced to The Who, the band is heard playing the closing chords of what appears to be "The Seeker".
 * The song played right before the end credits is "Won't Get Fooled Again" and not Homer's request of "Pinball Wizard".
 * The Simpsons' telephone number is given as 939-555-0113. The old area coded number of 636-555-0113 appears to connect to Mr. Burns; however, in "Lisa's Date with Density", his phone number was 555-0001.
 * The "angel skeleton" from "Lisa the Skeptic" can be seen in the wall dividing the cities.
 * One of the Simpsons comic books published by Bongo featured a similar plotline in which Springfield is divided over the issue of use and access to a lake.
 * The phone number for the exterminators is 983-7668 (X-TERM-N-8).
 * The drummer who plays with The Who in this episode is clearly a cartoon version of Keith Moon.
 * This is the first time Homer has had his body opened and his organs shown working. The second time was in "Treehouse of Horror XII" where the back of his skull was removed and his brain shown.

Cultural references

 * Homer imagines himself as a mayor, walking down the street in a Western town, wearing a cowboy hat and firing a rifle, in a parody of the opening credit of the Western show The Rifleman starring Chuck Connors.
 * Todd's woodpecker is a reference the Woody Woodpecker show, especially its laugh after attacking Bart.
 * The self-referencing blackboard gag refers to the presidential election which was two days after the episode was aired. A controversy surrounding the election was the supposed use of subliminal messages.
 * The timing of the episode coincides with Matt Groening's native northwest Oregon splitting into two overlapping area codes (Area code 503 and Area code 971). Such a split plan was often unpopular due to existing phone numbers changing, and now the alternative method of an overlay plan, whereby an area is given a new code for new numbers but existing numbers do not change.
 * While waiting for The Who's concert in Olde Springfield, Principal Skinner seems to be dressed in Mod attire. Edna Krabappel is dressed as a typical groupie.
 * The scene with Homer, Lenny and Carl having lunch in the nuclear power plant has a reference to the movie Pulp Fiction. While writing the new area code on his hand, Homer complains that he already has enough things to remember and a close-up of his hand shows the writing "Lenny=White, Carl=Black." This is a reference to the second last scene in Pulp Fiction, in which The Wolf is called to help resolve a problem. On a pad of paper before he meets up with Vincent and Jules, he writes "Vincent-White, Jules-Black" in order to distinguish between the two.
 * The last part of the final scene - where the badgers descend upon Springfield - shows one badger, much smaller than the rest, some distance behind the others. This is probably a reference to several similar Looney Tunes cartoons starring Sylvester, in which he is originally terrorised by a group of mice, but subsequently develops enough courage to "show them who's boss" and drive them all away. In each of these cartoons, the mice are shown fleeing the house, screaming and squeaking in fear, followed a little later by a baby mouse chattering incoherently in a voice that has been recorded at high speed.
 * Homer telling the Arizona Cardinals representative to "keep walking" is a reference to how poor the Cardinals franchise has been.
 * After they receive the gold from the river, Kent Brockman does an editorial about it and thanks Homer, saying that they will all be covered in golden showers (a sexual term for peeing on your partner). He does not get it but the people off to the side laugh hysterically.
 * When The Who orders Homer to tear down the wall, the moment is quite similar to movie The Wall by Pink Floyd, in which the main character is ordered to tear down the wall in his head, that alienates him from the world.

The Who references

 * When Kent Brockman's newscast shows a picture of Homer and friends on the steps of a home, the layout and poses match the back cover of The Who's Meaty Beaty Big and Bouncy compilation album.
 * Moe's line "That fat, dumb, and bald guy sure plays some real hard ball" is a variation of a lyric in the song "Pinball Wizard" by The Who. The original lyric is "That deaf, dumb, and blind kid sure plays a mean pinball".
