Intro: Kang and Kodos are watching the World Series, and find it extremely boring. So they use an accele-ray to speed it up so that it would be over in time for Treehouse of Horror. And things go wrong. It was pretty funny.
B.I. Bartificial Intelligence: Bart falls into a coma, so Homer and Marge replace him with a robot son named David. But then Bart recovers, and resents David. It was okay, but not great.
Survival of the Fattest: In a parody of The Most Dangerous Game, Mr. Burns invites a bunch of Springfielders to his estate... to hunt them. I applaud the choice of story to spoof, but I didn't really like the segment itself. And some parts of it I found offensive.
I've Grown a Costume on Your Face: This is the best part of the episode. Um... I mainly see it as a parody of the Buffy the Vampire Slayer episode Halloween, but Wikipedia also says it's a parody of Halloweentown II, and the Twilight Zone episode The Masks. (There's also a minor nod to Bewitched.) Anyway, a witch puts a curse on everyone in Springfield to become their Halloween costumes for real. For most of them, that's pretty unpleasant, though a few like it. And I definitely found a lot of the gags funny. (Honestly, without this segment my rating of the episode would have been lower than it is. On its own, this segment is worth at least three smileys.)
