Further, the rings circling Fun Homer are a parody of the energy cage rings that encircled General Zod and his two minions during their sentencing at the beginning of Superman II.
On the Simpsons' website; it stated that this episode aired on the same date but originally in 2005. This has since been corrected.
Skinner's car is seen as a pre-owned Toyota Camry, which Skinner quotes that 1995 was a good year for Camry models even though his car spent three months in a lake which he says while admiring it in the school parking lot. It is never seen again after this episode; according to the episode guide it says that the steam leak destroyed it with the school.
When Bart is on the plane in the flashback of the time he flew unescorted, the captain sounds a lot like Comic Book Guy.
In the German dub, this was the last episode in which Elisabeth Volkmann provided the voice of Marge Simpson. After Volkmann's sudden death in 2006, Anke Engelke took over. The German version of We're on the Road to D'ohwhere is dedicated to Volkmann.
Lisa wouldn't be able to get a job to support herself and Maggie because of her age and child labor laws. Most Springfielders are either really stupid or really greedy. And who's to say that Lisa can't lie about her age in order to find work? Besides, Bart got jobs in episodes such as "Lisa the Tree Hugger" and "Bart the Murderer", as well as Nelson later owning a bike shop in which he employed people later on in "Loan-a Lisa".
Also, Lisa would never have been left alone with Maggie as possibly the Flanders clan wouldve looked after Lisa with both parents missing or possibly Patty and Selma.
In one scene, Wendell was sitting in his classroom. Two scenes later, he was practicing with the school band in another classroom.
Much like Wendell, she can also be seen practicing with the school band in another classroom two scenes later. This is ok because the band is at a different time and is made up of kids from multiple classes and grades as seen in the opening credits Lisa is there as well as Milhouse, Sherri and Terri, as well as kids that are younger looking and/or not even part of the recurring known foreground cast.
Science classes dissect dead frogs, not live ones.
After the school was evacuated, Milhouse was seen in front of the school with other students. However, he was still in steam tunnels with Bart at that time, so he couldn't be outside.
Homer shouldn't be able to go to Las Vegas, as he was banned from there in "Viva Ned Flanders".
The episode's title is a take on the 1985 Talking Heads song “Road to Nowhere”. It may also refer to the famous series of Bob Hope/Bing CrosbyRoad to... movies, which have been spoofed multiple times by Family Guy. This is at least the third time the Talking Heads have been referenced by the Simpsons, not including "Dude, Where's My Ranch?".
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 testament to how long he had been dead.
