I'll give you that the latest episode wasn't that funny. But if you want funny, you should check out the Scientology episode, or even better, the episode telling the story of Joseph Smith. Absolute classics.
"the episode telling the story of Joseph Smith"
Still one of my favorites - Dumb Dumb Dumb Dumb Dumb!!
(Where was the outrage here after that? Oh that's right - making fun of Mormons is OK, I guess.)
