"Marjorine" episode of South Park

That is a pretty good episode for horror fans. Just casually watching it, I noticed some references to Pet Sematary, and also to that old short story "The Monkey's Paw." There are references to other horror movies in it too, as other people have noticed. Anyway, it's pretty funny. Butters's parents crack me up.... If you scroll down here, to "cultural references," there is a little discussion of what movies and stories it draws upon.
