South Park: Season 9 (2005)

Trey Parker and Matt Stone's quartet of foul-mouthed fourth-graders face a brand-new set of adventures in the series' ninth series, which opens with Mr. Garrison's notorious sex-change operation. Other highlights include Cartman battling the town's infestation of hippies and Kenny leading an army in heaven against Satan's minions (giving commands via a PSP game). Some of the series' best-known (and most divisive) episodes aired during series 9. Of particular note is "Best Friends Forever," which parodies the contentious right-to-die issue and earned the show its first Emmy Award for Outstanding Animated Program. The timely episode was obviously based on the case of Terri Schiavo, who died the day after the episode aired. The 12th episode of the series, "Trapped in the Closet," also attracted a fair share of controversy for its heavy criticism of Scientology and memorably features an extended sequence of scenes in which Tom Cruise, John Travolta and R. Kelly lock themselves in Stan's closet, with various characters and newscasters begging them to "please come out of the closet."
