Yeah. Mr. Mackey tried to find out who took a "dukey" in the urinal, and Cartman made up a conspiracy that Kyle was behind the 9/11 attacks. Then Kyle and Stan found out that the conspiracy behind the 9/11 attacks was a conspiracy by the government. Man it was great. Not as good as the WoW one, but it was still a knee-slapper.
Haha yes! That was also a very funny episode.
