BART BUYS LISA A CHRISTMAS GIFT THAT ISN'T WHAT IT SEEMS IN THE FIRST OF THREE BONE-CHILLING TALES OF THE STRANGE AND SUPERNATURAL ON "THE SIMPSONS" SUNDAY, DECEMBER 21, ON FOX

The frightfest begins with "Untitled Robot Parody" when Bart buys Lisa a knock-off of a Malibu Stacy convertible for Christmas. Later that night, the car morphs into a robot and instructs the other toys in Lisa's room to also transform. Soon, other giant robots appear and make Springfield the ultimate battleground. The scare-ific tricks continue in "How to Get Ahead in Dead-Vertising" when Homer accidentally kills Krusty. The clown's crooked lawyer enlists Homer to kill other celebrities so their likenesses can be exploited free-of-charge. For a fee, Homer goes on a killing spree and whacks Prince, George Clooney and William Shatner. Meanwhile in heaven, Krusty convinces other dead celebrities to stage a revolt and descend upon Homer. In the final Halloween scare, "It's the Grand Pumpkin, Milhouse," Lisa accompanies Milhouse to a pumpkin patch to await the appearance of the Grand Pumpkin. When he finally appears, the Grand Pumpkin goes on a rampage to avenge all pumpkins carved and tortured in the name of Halloween. And for an extra special trick-or-treat, the episode opener features Homer attempting to cast his ballot for the 2008 Presidential election with deadly results in the "Treehouse of Horror XIX" episode of THE SIMPSONS airing Sunday, Dec. 21 (8:00-8:30 PM ET/PT) on FOX.
