I saw something on Headline News over the weekend on their entertainment news show, and they were talking about South Park episode that lampooned Tom Cruise. Tom Cruise spent most of the show "in the closet", and one of the main characters begged Tom to "Come out of the closet", lampooning the rumor that he's homosexual, and they lampooned Scientology as a cult on that same episode.
That was a great episode!
The best episode was lampooning the Mormons. I laughed til I cried!
