The Comic Book Guy's line "Oohh, I've wasted my life..." just before his doom is creator Matt Groening's favorite line.
The producers had trouble with the censors over several segments in this episode. The opening segment of the episode, which features the aforementioned censor Fox Censor being stabbed to death, was pitched by David Mirkin and had a difficult time getting through the real-life censors. They had issues with the size of the knife and the sound effects used. Originally, the TV-rating was supposed to stab Censor with a dagger, but Fox objected because it was too gruesome and was changed to a cutlass. The censors also objected to an unaired scene where Homer does his naked church dance on an altar. The scene was reanimated so that Homer was dancing naked in the front row.
Scenes cut from the episode:
- In "The Homega Man", Krusty is walking out of a stage door of his studio making a reservation to a restaurant - but gets only static as the nuclear explosion passes by him and the studio, leaving him dead.
- In "Fly vs Fly", after Homer tells Marge that he's crazy, Marge tells Professor Frink that she is less interested in crazy gizmos and she's more interested in regular things - like for instance, cornholders. Most likely cornholders. She asks Frink if he has any cornholders, whereupon he gives her cornholders.
- In Bart's "Superfly" fantasy he saves Skinner from bullies - only to drop him into a volcano.
- Bart-as-fly discovers a group of flies on the corpse of a bird, causing him to go away in disgust.
In "Easy Bake Coven", the unnamed character portrayed by Edna Krabappel has a red "A" upon her frock. This is a reference to the main character in the book, 'The Scarlett Letter'. In the book, the "A" stands for adultery, and the woman is made to wear it by the townspeople as punishment for committing this crime. The implication that Mrs. Krabappel's character is likewise an adulteress fits with the series' numerous hints that Mrs. Krabappel has had many lovers.
Although Kang and Kodos make brief appearances in every Treehouse of Horror episode, their brief appearance in this one was nearly cut. David X. Cohen managed to persuade the producers to leave the scene in.
