"Treehouse of Horror XII" is the twelfth Treehouse of Horror episode of The Simpsons, aired in the show's thirteenth season. Because of Fox's contract with Major League Baseball's World Series, the episode first aired on the Fox Network in the United States on November 6, 2001, nearly a week after Halloween.


Outside Mr. Burns' manor, Smithers is standing on a ladder, trying to put up a small orange bat decoration on a weather vane. He slips on the ladder, grabs on an electric cord and slides down into an electricity box and gets zapped. A tower from Mr. Burns' mansion breaks in half, damaging a mausoleum, which opens up four caskets which in turn reveal three skeletons which all resemble Mr. Burns, dressed in various costumes. Later, we see the Simpsons dressed up in costumes, with Homer as Fred Flintstone, Marge as Wilma Flintstone, Lisa and Maggie as conjoined twins, and Bart as a hobo walking up to the mansion (with Bart and Lisa complaining that Flanders gave them toothpaste instead of candy). The family sees the building and caskets on fire, and screams in terror. They run out the gate, which as it closes, has its bars slice the family. The slices of the Simpsons continue to scream and run away. Mr. Burns, delighted, pats the orange bat as it comes to life and flies into the screen, revealing the title, "The Simpsons Halloween Special XII."

"Hex and the City"Edit

In a parody of the 1996 American body horror film Thinner, after he destroys the office of a gypsy fortune teller, the gypsy puts a curse on Homer, who is doomed to bring misery to everyone around him. The curse soon takes effect, with Marge growing a beard from her blue hair, Lisa turning into a centaur (starting with horse feet then going up to her armpits), Bart's neck becoming long and floppy as a result of Homer strangling him, Maggie becoming a ladybug with a human head, Lenny and Carl crushed by a helicopter, and Moe stuffed into his own pickled egg jar (with Homer wondering how that happened as he was talking to Moe). On Moe's suggestion, Homer sets out to find a leprechaun to end the curse. To get the leprechaun, Homer uses Lucky Charms cereal as bait, eventually finding a little Irish leprechaun after picking through a group of other magical creatures. Homer takes the leprechaun home, but it is extremely hyperactive and it runs amok. Homer takes the leprechaun to the gypsy’s office and sics it on her. Initially, the leprechaun lunges at the gypsy and the two of them roll around on the floor, fighting—until it turns into passionate kissing and fondling, much to Homer's disgust. The leprechaun and the gypsy get married, and are pronounced husband and wife by Yoda at a wedding attended by other gypsies and mythical creatures, as well as the Simpson family. Homer then remarks how everything ended happily, but a now fully hair covered Marge reminds him that Bart committed suicide by drowning in his cereal, and says that apologizing will bring him back to life. Out of sheer pride, Homer refuses.

"House of Whacks"Edit

In a parody of Demon Seed and 2001: A Space Odyssey, the Simpsons buy an automated upgrade for their home called "Ultrahouse", which comes with three celebrity voices: Matthew Perry, Dennis Miller (whom Lisa and Marge recognize as "the voice that caused all those murder-suicides"), and Pierce Brosnan (which Marge picks because he was on the show Remington Steele). Marge finds the house, which does all the work for the Simpsons, charming. The house soon becomes infatuated with Marge after the two share a bath and decides to kill Homer after having a conversation with him about how lucky he is to be married to Marge (with Homer admitting that the only reason she is married to him is because he knocked her up). In the middle of the night, the house lures Homer downstairs by frying bacon. The next morning, Marge fears that Homer is dead and attempts to escape the house with the kids, but Ultrahouse locks her inside and tries to subdue and seduce her. When Marge and the kids rush to the kitchen, they find that Homer is alive, but has cuts all over his body and a gaping hole in the back of his head. After the house attempts to kill him in many ways, Homer leads a charge to the basement where he attacks the CPU’s "British charm unit" (but not before chopping up the water softener, with Homer acknowledging the mistake by stating, "Well I am missing the back of my head. I think you [Lisa] can cut me some slack!"), which makes it speak with a rude American dialect before powering down and finally shutting off. Feeling bad that she has to toss out the Ultrahouse (since he was charming and witty before being driven mad by love), Marge gives the CPU to her sisters Patty and Selma, whose mundane stories about their day at work drives the CPU to suicide (but since the CPU is not willing to reach inside Selma's cleavage to get his self-destruct button, the Ultrahouse CPU is reduced to banging himself with Patty and Selma's Egyptian pyramid lamp).

"Wiz Kids"Edit

In a world parodying that of Harry Potter, Bart and Lisa go to the "Springwart’s School of Magicry" in which young boys and girls are trained in the art of witchcraft, such as turning frogs into princes, with Lisa's turning into a perfect British one while Bart's results in a freakish, vomiting hybrid begging only for death. Lord Montymort notices Lisa’s spells and he and his snake sidekick, Slithers decide to capture Lisa in order to increase his power. Montymort looks for someone to assist him and chooses Bart, who agrees to Montymort’s proposal. On the night of the magic recital at Springwart’s School of Magicry, Lisa attempts a "levitating dragon trick" on a gigantic dragon that is released onto the stage. Lisa is shocked to find that her spell will not work, and then notices that Bart has replaced her wand with a Twizzler. The dragon morphs into a giant Montymort who captures Lisa and begins sucking up her power. Bart casts a spell (to destroy the evil one) against Montymort, but is struck by lightning. In a last-ditch effort, Bart charges at Montymort and stabs him in the shin with his magic wand. Montymort dies (as his shin was the source of all his magic) and is eaten by a crying Slithers. Bart and Lisa walk away, trying to forget everything that happened (unaware that the leprechaun from the first story is right behind him).


Pierce Brosnan, the Leprechaun, and the freakish Frog Prince exit a trailer, with fruit baskets. After the Leprechaun and Frog Prince (who were also apparently guest stars) criticize Brosnan for being allowed to park so close to the set in such a vastly large parking lot, Brosnan offers them a ride to their car. As Brosnan pulls out, he finds out too late that he has been taken hostage as they drive out of the parking lot in a mad haste.


As with the rest of the Halloween specials, the episode is considered non-canon and falls outside of the show’s regular continuity. This was the first Halloween special where the writers did not have "scary names" in the credits. This was due to the terrorist attacks on September 11, after which the staff were "trying to be sensitive", and, according to producer Ian Maxtone-Graham, the Halloween names would all reference the attacks had they been kept. Mike Scully, who worked as show runner for the episode, stated that the "scary names" were removed because they had also "turned into shameless plugs" for side projects done by The Simpsons staff members.

The first segment, "Hex and the City", was written by Joel Cohen. The gypsy fortune teller in the segment was portrayed by Tress MacNeille while the leprechaun was played by Dan Castellaneta. Current show runner Al Jean stated in the DVD audio commentary for the episode that the leprechaun seen at the end of the segment was "as much as [he] had ever laughed" at the color screening for the episode. He stated that the way the leprechaun moved and the way Reardon directed it was "just so funny". The leprechaun has reappeared many times since the episode, becoming one of few characters on The Simpsons to "leap from Halloween [shows] to regular shows".

"House of Whacks" was co-written by John Frink and Don Payne. Payne, who conceived the story of the segment, based it on Stanley Kubrick’s film 2001: A Space Odyssey. The segment would originally end with the Ultrahouse killing Homer, and, for compensation, the family would program the house with Homer’s personality. The Ultrahouse was portrayed by Pierce Brosnan, however he was not the staff’s first choice for the role. The role was originally intended for Sean Connery, and over the course of production, the staff considered Lyle Lovett and Gary Oldman for the role. The decision remained until "someone who worked for [Lovett] decided it was somehow insulting to have him play a house", according to Scully. At this point, the staff settled on Brosnan. Scully stated that "Brosnan wound up doing a great job" and that working with him was "really funny". Originally, the Ultrahouse would have a pompadour and play the guitar, however they changed its mannerisms to suit Brosnan’s performance better. Matthew Perry also made a guest appearance, playing himself as one of Ultrahouse’s voice options. Regular cast member Dan Castellaneta portrayed Dennis Miller in the segment (a special ending credit had to be made to avoid confusion with viewers who thought the real Dennis Miller did voicework on the show). One scene was cut from the segment. The scene would take place during Marge’s call to the police station, where police chief Clancy Wiggum, while answering Marge’s call, is being shot at by "RoboCops".

The third segment, "Wiz Kids", was written by Carolyn Omine. Omine stated in the DVD audio commentary for the episode that the segment was "a really hard sell", since only about four of the writers had read Harry Potter and the Philosopher’s Stone, the book the segment was based on, while the rest of the writers did not know about the book and thought viewers would not know who Harry Potter was. At the time of the episode’s production, four books had been written in the Harry Potter book series and the film adaptation of Harry Potter and the Philosopher’s Stone would be released at the end of November, the same month that this episode aired. Two scenes were cut from the segment; one of them would serve as an extension of Montymort and Slithers plotting their scheme, followed by a scene showing Bart combing his hair, while the other scene would show Groundskeeper Willie riding an enchanted lawn mower. The latter scene was cut for time.

Cultural referencesEdit

The title of "Hex and the City" is based on the title of the television show Sex and the City. The segment contains a background character who looks similar to the main character from Caps For Sale, a 1938 children’s book about a cap salesman who wears all his hats. Cedars-Sinai is a hospital in Los Angeles. One of the bunnies jumping into the pit that Bart and Homer dug is Bongo, the one-eared rabbit character from Simpsons creator Matt Groening’s comic Life in Hell. Among the creatures Bart and Homer find in the pit is journalist and news personality Katie Couric, as well as a pixie resembling Tinkerbell. The priest at the leprechaun and the gypsy’s wedding is Yoda, a character from the Star Wars franchise. Maaggie turns into a ladybug similar to The Metamorphosis.

The plot of "House of Whacks" is based on the science-fiction film 2001: A Space Odyssey by Stanley Kubrick, with Ultrahouse acting as a reference to HAL 9000, the antagonist of the film. The Ultrahouse’s fascination with Marge was inspired by the science-horror film Demon Seed by Donald Cammell. The Ultrahouse wears gloves similar to those worn by Mickey Mouse. To attack Homer, the Ultrahouse uses, among many other weapons, an automatic hammer resembling the one Homer invented in the episode "The Wizard of Evergreen Terrace". "Wiz Kids" bases its plot on the Harry Potter books written by J. K. Rowling, who would later make a guest appearance in the episode "The Regina Monologues".

Like many episodes from 21st century seasons, “XII” doesn’t present many significant flaws, but it also doesn’t ever really shine. Some good moments pop up here, mostly due to vocal performances. ...Nonetheless, the overall tone seems a bit lame. ...“XII” isn’t bad Simpsons, but it’s mediocre.
Colin Jacobsson, DVD Movie Guide

Following its television broadcast and the home video release of the thirteenth season of The Simpons, "Treehouse of Horror XII" received mixed reviews from critics. Casey Broadwater of stated that the episode "is merely so-so entry in the show's annual Halloween anthology", while Colin Jacobsson of DVD Movie Guide wrote that, while it "doesn’t present many significant flaws", it also "doesn’t ever really shine". He concluded his review by writing “'XII' isn’t bad Simpsons, but it’s mediocre”. Writing for Good Film Guide, Matt Wheeldon held a similar opinion, calling it “an average quality Treehouse of Horror episode” and described it as being “easily watchable” and “fairly memorable, but far from the best of the bunch”. Nate Boss of Project:Blu stated that the episode is “At times memorable, at times forgettable” and that it “kicks off Season 13 with a smile, whimper, and thud”. Ron Martin of 411Mania stated that, while he does not consider “Treehouse of Horror XII” to be the worst episode of the series, “as far as Treehouse episodes go, it has to be one of the weakest”.

Writing for Suite101, Dominic von Riedemann described the episode as a “disappointment”. Reviewing the episode for the Daily News of New York City before the episode's official broadcast, Eric Mink complimented it for being “fitfully funny”, however he added that the episode “seem[s] short on the pop-culture digs and celebrity skewering that used to put a high gloss on the show's gleaming reputation”. Jennifer Malkowski of DVD Verdict however gave the episode a positive review, and referred to the episode, along with “Weekend at Burnsie's”, as the two best episodes of the season. She wrote that “[the episode] succeeds because of wall-to-wall laughs”, and cited several scenes and gags, in particular the “horrible vomiting frog ‘prince’ that Bart enchants”. She gave the episode an A– rating. Aaron Peck of High-Def Digest was also favorable, stating that the episode was “one of [his] all-time favorite Treehouse of Horror episodes”.

“Hex and the City” garnered mixed responses from critics; Broadwater wrote that the segment was “a bit of a letdown” while Boss described it as “fairly poor”. Mink however felt that the segment was the best in the episode. “House of Whacks” was well received. Broadwater described the segment as “brilliant” while von Riedermann referred to it as being the best of the three. Boss, who was dissatisfied with the first segment, felt that “House of Whacks” “makes up for it”. Brosnan's guest appearance was praised; Jacobsson described the performance as “a surprisingly nice guest turn” while Boss referred to it as “killer”.Adam Rayner of Obsessed With Film wrote that the segment features Brosnan “giving his best acting turn since… ‘The Long Good Friday’?”. Particular scorn was aimed at “Wiz Kids”, the third segment of the episode. Jacobsson stated that “Wiz Kids” “ends the show on a drab note” while Mink stated that the segment “pretty much fall[s] flat”. Boss was also critical, writing “Harry Potter, in my Simpsons? It may be more likely than you think, although, for sure, it really does stink”. Andre Dellamorte of Collider wrote that, even though he complimented the segment for being “bold” considering the film it parodied had not come out yet, he criticized the segment by writing “the depth of the parody stops with surface references”.Peck, however, described the segment as being “quite possibly one of the best and most clever spoofs of Harry Potter”.
