Trivia: The property next to the Simpson house is very versatile. It has been Flanders house (both sides), a cemetery, the parking lot to the nuclear plant and a vacant lot.
Trivia: During the couch gag, the Simpsons run through different places (as spoofs of different TV shows). One of the places they run through is the bar from Cheers. When they all sit down, Sideshow Bob walks through the door. Kelsey Grammer does the voice of Sideshow Bob, and starred as Doctor Frasier Crane in Cheers.Casual Person
Trivia: In this episode the Simpsons are labeled finally as a "northern Kentucky family"; this was quickly enough dismissed as a red herring for various reasons. To further mystify, however, if you turn on the English subtitles on the episode, they say "southern Missouri family".
Trivia: In this episode, Wolfcastle says "Real acid?" and starts to have doubts about filming the scene. In The Terminator, Arnie (who Wolfcastle is a parody of) said the exact same thing when he learned that the crew were going to pour acid on his clothing for a smoke effect.
Trivia: Smithers made his first appearance in this episode but he was mistakenly animated with the wrong colour. He was made into an African American with blue hair. This was corrected in the episode "There's No Disgrace Like Home", where he appeared in his normal yellow colour.
