The Simpsons have a Halloween party and tell 3 stories:
Clown Without Pity- For Bart's birthday, Homer needs to get him a present at the last minute because he forgot. He ends up getting a Krusty Doll that is seemingly evil and wants to kill Homer.
King Homer- A parody of King Kong. Not my favorite, it is actually my least favorite. Not very funny.
Dial Z For Zombies- Bart raises the undead and now the Simpsons need to get rid of all the zombies before it is too late.
The first and last segments are the best but the third is weak IMO
