This episode marks the first time one of the male Simpsons voice actors does a female character. Dan Castellaneta voices the laughing old lady in North Haverbrook. (edit) Conan O'Brien called George Takei to be in this episode, but he turned the part down. It instead went to Leonard Nimoy. (edit) Conan O'Brien declared this episode as his favorite. (edit) The Monorail Song was actually written by Jeff Martin, Conan O'Brien, John Swartzwelder, Jon Vitti, Al Jean, Mike Reiss, George Meyer & Frank Mula. (edit) Blackboard Joke: I will not eat things for money.
Couch Gag: The family sits down, followed by the show's whole cast sitting in front of them. (edit)

Marge: How fast is it going?
(Sees Homer scream in the speeding monorail passing by.)
Scientist: Well, judging by your husband's cowardly scream, 480 miles per hour. (edit) Kent Brockman: What have you been up to, Lurleen?
Lurleen Lumpkin: I spent last night in a ditch. (edit) Leonard Nimoy: A solar eclipse: the cosmic ballet goes on.
Man sitting next to Nimoy: Does anybody want to switch seats? (edit) Marge: Homer, there's a man here who thinks he can help you!
Homer: Batman?
Marge: No, he's a scientist.
Homer: Batman's a scientist.
Marge: It's not Batman! (edit) Marge: We're too late!
Cobb: I shouldn't have stopped for that haircut. Sorry. (edit)

Lurleen Lumpkin, from "Colonel Homer," makes a cameo as a washed-up celebrity. (edit) One of the paintings in the monorail luxury bar area is the Led Zeppelin symbol, the burning Hindenburg. An eerie fore-shadowing of the monorail. (edit) Sign at Swampy's Liquor on Main Street reads: "Duff Spoken Here" (edit) Matt Groening's favorite line from this season comes when Homer says, about a group of possums living in the monorail, "I call the big one Bitey." (edit) The three "escalator to nowhere" patrons are caricatures of directors Rich Moore, Wes Archer, and supervising director David Silverman. (edit)

Beverly Hills Cop
When Smithers and Burns are hiding the green ooze, the music bears a striking resemblance to the "Axel F" theme from this movie. (edit) Child: Is Superman faster than The Flash?
This question the child asked was based on the Superman comic book and the episode, "Speed Demons." (edit) Homer: Batman's a scientist.
Aside from this quick joke, Simthers' and Burns' escape is a parody of the power zip-cord from the film Batman. (edit) The Flintstones
Homer leaving work and his drive home is a parody of The Flintstones intro and theme.
(edit) Lyle Lanley: Based on the quick-talking con man Harold Hill from Meredith Wilson's musical "The Music Man". (Both characters convince the townspeople to go for their cons by taking over a town meeting with a catchy patter song. Harold Hill's is "Ya Got Trouble".) (edit)
