Treehouse of Horror XII

Intro: The Simpsons (all dressed as characters from previous Treehouse of Horror episodes, save Lisa, who is an axe murder victim) watch Kang and Kodos's lame attempt at a Halloween variety show. I Know What You Diddily-Iddily Did – Marge accidentally runs over Ned Flanders and is haunted by claims that someone knows what she did, only to realize that Ned survived because he became a werewolf. Desperately Xeeking Xena – Bart and Lisa gain super powers after a freak accident at school and must save Lucy Lawless (dressed as Xena) from the Collector (Comic Book Guy). Life's A Glitch, Then You Die – When the Y2K bug causes everything electronic and computer generated in the world to go haywire, the family searches for a way out.

G-G-Ghost D-D-Dad – Homer dies after eating broccoli and must do one good deed in order to get into heaven. Scary Tales Can Come True – In a mixed parody of many Grimm's Fairy Tales, peasant children Bart and Lisa are sent to live in the woods, where they inadvertently set up Goldilocks to be killed by the Three Bears and meet a witch with a gingerbread house. Night of the Dolphin – Dolphins take over the world after Lisa frees their leader from an aquatic animal park.

The 13th Treehouse of Horror episode, consisting of three self-contained segments. Send in the Clones – Homer buys a hammock that can produce clones of himself. He creates numerous clones to help him around the house, but they soon overrun Springfield. The Fright to Creep and Scare Harms – Lisa petitions the town to get rid of their firearms after discovering the gravestone of a young man named William Bonney who died from gun violence. However, Lisa soon discovers that William Bonney is the real name of Western outlaw Billy the Kid, whose ghost, along with the ghosts of other infamous criminals, takes over the defenseless town. The Island of Dr. Hibbert – Dr. Hibbert invites the citizens of Springfield to his island resort, where he turns them into animals.

Dial M for Murder or Press "#" to Return to Main Menu - In this homage to Alfred Hitchcock's supense/murder mysteries, Lisa teams up with Bart to get revenge on their teachers after Ms. Hoover sends Lisa to detention, but the plan goes awry when Bart kills Ms. Hoover and wants Lisa to murder Mrs. Krabappel. Don't Have a Cow, Mankind - In this send-up of such zombie/apocalypse horror films as 28 Days Later and Children of Men, Krusty the Clown introduces a new hamburger that zombifies the entire town -- except for Bart, whose natural immunity to the burger becomes the key to stopping the zombie attacks. There's No Business Like Moe Business - In this Sweeney Todd-esque musical, Moe creates a new beer that becomes a sensation — thanks to Homer being impaled on the microbrew machine and bleeding into the beer supply.

This episode features a segment that parodies the Twilight novel and film series. Daniel Radcliffe, star of the Harry Potter film series, will guest star in the segment. Hugh Laurie will guest star in a segment that parodies Dead Calm. In two other segments there will be an Office parody and another segment in which toys come to life.

The Diving Bell and the Butterball - A spider bite leaves Homer paralyzed but he is able to communicate through natural gases. Dial D for Diddly - Ned Flanders becomes a serial killer. In the Na'Vi - Bart and Milhouse are assigned to access a sacred extract of a distant planet.

This year's Halloween special: -An untitled introduction in which a botched human sacrifice during the Mayan empire leads to the apocalypse said to happen in the year 2012. -The Greatest Story Ever Holed: Professor Frink's Subatomic Supercollider releases a black hole that Lisa takes in as a pet -- and ends up sucking up all matter in the world thanks to everyone tossing their trash into it. -UNnormal Activity: In this parody of the Paranormal Activity movies, a collection of video clips show viewers demonic activity happening in the Simpsons' house late at night -- which may have something to do with Marge's deal with the Devil she made years ago. -Bart and Homer's Excellent Adventure: In this Back to the Future parody, Bart steals Professor Frink's time-traveling car and heads to 1974 so he can buy a Radioactive Man comic at cover price (25 cents instead of the present-day price of $200), but his visit into the past alters the future, causing Marge to marry Artie Ziff.
