During the trip, they're listening to the song "You And Me And The Bottle Makes Three Tonight" by Straight No Chaser.
During the song, Kirk messages Homer saying that he has watched The Godfather and completed Halo. He also says "designing the world's best Blues Brothers fanpage" while dressed as the main characters of the film.
At the end of the episode, drunk Kirk says that "Jet fuel can't melt steel". This is a reference to a famous conspiracy theory around the September 11 terrorist attacks that claims that the planes alone would not be able to take down both towers.
