The Simpsons

Marge hopes to save Springfield Elementary by inviting a reclusive British children's author (guest star Emma Thompson) to appear at the school's book fair. But Homer botches his assignment of picking the author up at the airport, and the drunken pepper pot leads him on a desperate wild chase to get her to the school on time.

Bart and Lisa adopt an abandoned baby chimp and clash over their surprisingly different parenting styles. When the chimp is abducted by a private wild animal zoo, the family goes on a mission to rescue him. Homer is conflicted about saving the ape, because he's convinced the chimp will tear off his face and groin.

All hell breaks loose on Halloween when a killer comes to Springfield and hacks their way through town. No Simpson is safe from. THE REVENGENING!

In this year's extra-scary, ultra-spooky Treehouse of Horror, Marge gets a horrifying new perspective on marriage; Bart and Santa's Little Helper embark on a bone-chilling adventure; and Homer takes a driving lesson.
