|Treehouse of Horror||
- This is the only Treehouse of Horror episode to have the Treehouse motif, despite the word "Treehouse" in the title of all Halloween specials.
- This is the first time that the Simpsons family have a barbecue.
- The tombstones at the beginning read from first to last, and left to right, in all caps: Ezekiel Simpson, Ishmael Simpson, Cornelius V. Simpson, Garfield, The Grateful Dead, Casper, the friendly boy, Elvis, Your name here, Paul McCartney, disco, and Violence on TV.
- McCartney's gravestone is a reference to the "Paul is dead" hoax of the 1960s.
- Homer overuses lighter fluid for a barbecue again in Lisa the Vegetarian.
- "Bad Dream House" parodies a number of haunted house films. The opening image of the house shows that one side resembles the house from "The Amityville Horror" house. Much of the plot follows the events of the film "Poltergeist," such as a scary tree right outside Lisa's bedroom, and the implosion of the house at the end a la The Fall of the House of Usher. The comparison to 2001: A Space Odyssey is also quite fair, although much more obvious references are made in later episodes.
- Bart, as the Raven, knocks several of Edgar Allan Poe stories off the bookshelf, including "The Pit and the Pendulum," "The Tell-Tale Heart," and "The Purloined Letter."
- The book "To Serve Forty Humans" is a reference to The Twilight Zone episode where strange aliens greet humans with a book, which translated means "To Serve Man," and solved all the problems of Earth. Curious Earthlings accept invitations of the aliens to see their home world and travel on their spaceships. One man accepts such an invitation, but is stopped by his coworker, who has properly translated the book and shouts, right as he's getting on a spaceship, "It's a cookbook!"
- Edgar Allan Poe is credited as a writer for this episode.
- This is the only Halloween episode with the normal Gracie Films logo sequence; from Treehouse of Horror II it features a pipe organ playing its jingle, and Treehouse of Horror IV onwards, a horrific and loud scream replaces "Shh."
- This is the first Treehouse of Horror in which Kang and Kodos don't try to conquer Earth.
- This is the first Treehouse of Horror not to have the cast's names changed due to Halloween (e.g. "Bat Groening" instead of Matt Groening).
- The Indian Burial Ground under the house in "Bad Dream House" contains graves of:
- In "Hungry are the Damned," when the Rigellians are measuring the Simpsons's weight, along with Kang, Kodos, and Serak, there is a fourth unnamed Rigellian with them that does not appear for the rest of the episode.
- This is the first appearance of Kang and Kodos and (the only appearance of) Serak the Preparer.
- In "Bad Dream House" the house chants, "Die, die, everybody dies." This line and its cadence were later utilized in the 2008 direct-to-video horror film Trailer Park of Terror.
- In "The Raven", Homer was reading Forgotten Lore, Vol. II. This is a reference to the second line of the poem, in which the narrator is pondering "Over many a quaint and curious volume of forgotten lore."
- Marge's warning at the beginning was put in, just because the producers genuinely thought this episode was scary for younger viewers.
- The plot of telling scary stories comes from the Tracey Ullman short Scary Stories, and would also reappear in Treehouse of Horror III.
- All the segments had different people working on them, unlike the following episodes.
- For unknown reasons, on FXX reruns instead of using its own credits music it uses the one from Treehouse of Horror XIII.
- Frankenstein: Marge warns the audience that the show is very scary.
- Psycho: The house's shape.
- Recess: This episode from Recess Terrifying Tales of Recess" is similar.
- Life in Hell: Binky appears as Maggie's toy.
- The Amityville Horror: Blood streams from the walls.
- The Exorcist: Maggie turns her head 360 degrees.
- Poltergeist: The house is built on an ancient Indian burial ground and the scary tree outside Lisa's bedroom and the house implosion.
- The Fall of the House of Usher: The house implodes.
- The Fly: A fly cries out, "Ow!" as it hits a bug zapper.
- Twilight Zone: The dust-blowing sequence.
- The Raven: Lisa reads this story.
- The Cask of Amontillado: Homer's cup has Amontillado written on it.
- Lenore: The character Lenore also appears in The Raven.
- The Pit and the Pendulum: Raven Bart drops this on Homer's head.
- The Telltale Heart: Raven Bart drops this on Homer's head.
- The Purloined Letter: Raven Bart drops this on Homer's head.
- Friday the 13th Part I: Bart compares how The Raven used to be scary to this.
