Mystery of the Urinal Deuce
Cartman researches 9/11 online, and delivers a presentation to his class where he claims the true culprit behind 9/11 was Kyle. Despite the absurdity of Cartman's claims, he nonetheless convinces everyone that Kyle is guilty. Kyle enlists Stan's help, and they leave South Park to find an organization that can prove Kyle's innocence. The group they find, however, believes that the United States government orchestrated the 9/11 attacks. A SWAT team attacks and takes Kyle, Stan, and the leader of the conspiracy organization to the White House where U.S. officials, including President George W. Bush, reveal that the government "really is" behind 9/11. Bush murders the conspiracy leader and decides to kill Stan and Kyle as well, but they flee.
