We're on the Road to D'oh-where/References

Trivia

 * When Homer refers to Oregon as "the birthplace of Matt Groening," he mispronounces the show creator's last name as "Gro-ning," a spoof on the common error. The Simpsons show creator's last name is correctly pronounced "Gray-ning."
 * This episode disproves the common fan theory that Springfield is in Oregon because Homer must drive to Oregon from Springfield's location.
 * Birch Barlow (the show's parody of Rush Limbaugh) can be seen at Marge's "garage sale" buying drugs, a parody of Limbaugh's drug addiction.
 * Myra, Principal Skinner's secretary, makes her first appearance in this episode. Her voice sounds similar to the late Doris Grau who voiced Lunch Lady Doris
 * Serious Homer is dressed in Homer's conductor uniform from "Marge vs. the Monorail".
 * Further, the rings circling Fun Homer are a parody of the energy cage rings that encircled General Zod and his two minions at the beginning of Superman II.


 * On the Simpsons' website; the simpsons.com it stated that this episode aired on the same date but originally in 2005. This has since been corrected.
 * Homer says during a conversation with Bart: "I'm 38 years old, driving a crappy car, with a son who doesn't respect me, and I'm one Snickers pie away from losing my foot to diabetes." This unusually dark statement was arguably out of character for The Simpsons and Homer, who usually takes a happy-go-lucky approach to life and who shies away from serious discussion with his son. Also, Homer has usually been identified as 39 years old in recent episodes.
 * Skinner's car is seen as a pre-owned Toyota Camry, which Skinner quotes that 1995 was a fine year for Camrys, even though his spent three years in a lake which he says while admiring it in the school parking lot. It's never seen again after the episode, according to the episode guide it says that the steam leak destroyed it with the school.

Cultural References

 * We're on the Road to D'ohwhere is a take on the Talking Heads song Road to Nowhere. It may also refer to the famous series of Bob Hope/Bing Crosby Road to... movies, which have been spoofed twice by Family Guy. This is at least the third time that the Talking Heads have been referenced by the Simpsons, not including  "Dude, Where's My Ranch?"
 * The song the band class plays is "Louie, Louie".
 * The song Flanders sings is the chorus from the hit Andrew Lloyd Webber musical Joseph and the Technicolor Dreamcoat.
 * Intellectual Homer, who has been killed by Serious Homer, has written on the floor in his own blood "Ontogeny recapitulates phylogeny". This is the famous statement of Ernst Haeckel's recapitulation theory about the similarity of the embryonic development of organisms to its evolutionary history. Ironically, it has been debunked as a scientific principle. Presumably, Intellectual Homer wrote this before it was debunked, a testement to how long he had been dead.
