Billy: That's just a tree branch...with a nice watch on it! (steals watch)
Latex Perfection: During Lisa's nightmare sequence when in the cemetery, at one point she winds up on the lap of an old lady that reassures her "Grandma will protect you," before peeling off her mask to reveal a skull that says (in a male voice) "But I ain't Grandma!" and swallows her.
Offscreen Teleportation: Chief Wiggum is naked and at the top of a tree and Lou is trying to convince him to get down. As soon as Lou offers him a donut, Chief Wiggum appears next to him and fully dressed to pick it. Lou is visibly surprised.
Precision F-Strike: At one point, Homer says "That's bullshit, man!" (with "shit" bleeped out, making this one of the few times a character intentionally says a swear word that warrants a bleeping on network television and not as a joke, like when Homer swore at the ambulance on "Guess Who's Coming to Criticize Dinner?").
