- An Aesop: It's okay for anyone, including "smart" people, to be scared.

- It's Probably Nothing/Suspiciously Specific Denial: Occurs with Groundskeeper Willie's cousin, Gravedigger Billy, who tells Lisa that if somebody was buried alive, a bell placed on the grave would ring.Billy: Oh, that's just the wind.
(a hand bursts through the grave)

- 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.

- Precision F-Strike: While the kids watch a Land of the Wild Beasts-themed advertisement for the Hillside Wrangler Steak House (as part of a presentation for the author's art), a jumbo shrimp appears saying he has a maximum of two servings, prompting Homer to stick his head into the theater and say, "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?")
- Shout-Out: The Land of the Wild Beasts is a parody of Where the Wild Things Are.
- Stating the Simple Solution: The Beasts tell Lisa that she could just close the curtains so she won't see the cemetery. Also a nightlight but Homer finds it too expensive.
