Treehouse of Horror XIII


  • Aside from the titles, Hex and the City and Sex and the City-an HBO television series at the time which explored four women's sexual habits- were not at all similar. If anything, Hex and the City more closely parodied the 1992 Married With Children episode "Psychic Avengers," which featured the Bundy family cursed for breaking a gypsy's crystal ball; like Homer, Kelly Bundy would also use Lucky Charms, but clutched the cereal box with hopes of avoiding bad luck rather than using the Lucky Charms cereal as bait for catching a leprechaun.
  • This is the final Halloween episode where the title says "The Simpsons Halloween Special." Starting with "Treehouse of Horror XIII", the words "Treehouse of Horror" will be in its place in the title before the roman numerals.
  • "Treehouse of Horror XII" was originally scheduled to air on Sunday, November 4, 2001. It was delayed two days when the 2001 World Series started, which was delayed after the September 11 attacks and was also televised on FOX, and went to seven games. As a result, "Treehouse of Horror XII" is one of the few episodes of The Simpsons to air in a different time slot on American TV. Because of this, this episode ended up airing on Tuesday, making it the first episode to air on that day.
  • The "Burns family corpses" in the opening sequence are as follows (from left to right as seen on-screen):
    • A man's body that somewhat resembles General Douglas MacArthur as it is wearing an Army uniform and has a pipe and sunglasses like MacArthur's; however, it's a three-star general and MacArthur was a five-star. The body has a tomahawk stuck in its chest.
    • A man's body dressed as a pirate. It has a patch over its left eye and a cutlass stuck in its right eye socket.
    • A woman's body, dressed as a burlesque dancer (or a prostitute from the Old West), with three bullet holes in its forehead.
    • A man's body wearing a suit of armor with a pitchfork stuck through the helmet's eye slits.
  • Some of the mythical creatures that Homer and Bart caught with the Lucky Charms are: Imp, fairy, pixie (Tinkerbell), hobgoblin (mistaken as a goblin by Bart), nymph, naiad, woodsprite, Katie Couric and a leprachaun.
  • At the end of the "Hex and the City" segment, Homer is first seen at the Leprechaun/Gypsy wedding in his regular outfit, a white t-shirt and blue jeans. In the next scene, however, Homer is seen close-up wearing a formal blue suit.
  • Other people who were friends and families of Homer didn't get cursed, such as Abe Simpson, Mona Simpson (Mona was a minor character until her death), Herb Powell, Barney, Charlie, Sam, and Larry. However, they could have been cursed off-screen.
  • One of the gypsies at the wedding bears a strong resemblance to Ruth Powers.
  • The voice of the Salesbot in "House of Whacks" is very similar to Gil's.
  • One of the items the Ultrahouse 3000 attacks Homer with is the electric hammer Homer invented in "The Wizard of Evergreen Terrace".
  • In "Wiz Kids," Lord Montymort's "wailing wall" features Krusty the Clown, Maude Flanders, Comic Book Guy, Snake Jailbird, Bleeding Gums Murphy, Rainier Wolfcastle, Kent Brockman, Mr. Largo, Patty Bouvier, Blue-haired Lawyer, Üter Zörker, Old Jewish Man, and Frank Grimes.
  • Lord Montymort attempts to speed up the process of removing her magical essence by turning her upside down and patting her like a ketchup bottle.
  • This is the second Treehouse of Horror episode that does not have the cast's names changed due to Halloween e.g. Bat Groening. Some of this was in part due to the 9/11 attacks. This was clearly done late in the production process, as the text appears very digital and less natural than it usually does.
  • All of the episode writers' names return to the opening credits in this episode, rather than each segment's writer(s) names appearing at the beginning of each segment (as in "Treehouse of Horror X" and "Treehouse of Horror XI").
  • This is the last Halloween episode to use traditional cel animation, starting with "Treehouse of Horror XIII", all Halloween specials were digitally animated.
  • This episode marks the first of a few things:
    • It’s the first episode with the Gracie Films Logo with Homemade Shush and Music.
    • It’s also the first episode to air after 9/11.

Spells used in "Wiz Kids"

Caster Incantation Result


"Abraca-dairy!" A pitcher filled with milk appears and pours its contents onto Bart's cereal.
Lisa "Five minutes more-ious!" Time turns back five minutes, prompting Marge to object: "That's not good for the clock."
Nelson "Stop zapping yourself!" Nelson grabs Milhouse's wand and touches it to his head (while Milhouse is still holding the wand). Milhouse's head successively turns into a banana, an ostrich head, and Mr. T's head.
Milhouse "Slimy Prince Limey!" Milhouse's toad turns into a drunken loutish prince who hits on Mrs. Krabappel.
Lisa "Hocus-croakus!" Lisa's toad turns into a handsome prince, whom Mrs. Krabappel hits on.
Bart "Abra-ca ... turn into a prince guy?" Bart's toad turns into a hideous toad-prince creature, which constantly vomits and asks Bart to kill him.
Lisa "Head Zeppelin!" Bart's head turns into a Zeppelin and he floats toward the classroom ceiling.
Milhouse None (The Invisibility Cloak) Milhouse is supposed to turn invisible, but instead his clothes disappear, leaving him standing naked on the stage at the Magic Recital.
Principal Skinner None (Amnesia Dust) Skinner uses the Amnesia Dust twice at the Magic Recital: 1) To make the audience forget Milhouse's performance, and 2) To make the audience forget a bad joke he tells.
Lisa "Alakazai-dragonfly!" Nothing happens. The spell is presumably supposed to lift the dragon into the air, but Bart stole Lisa's wand and left a black Twizzler in its place. The dragon reveals itself to be Lord Montymort in disguise and grabs Lisa.
Bart "Prank be undone! Destroy the evil one!" Bart casts the spell with Lisa's wand, trying to save her by attacking Montymort, but instead he zaps himself.
