Oh my God, they killed Chef! YOU BASTARDS!!
So Chef runs away to join a “Super Adventure Club” which brainwashes him into wanting to have sex with children. In true South Park style, they not only parody the issue at hand, but also themselves by making it hilariously obvious that they are cutting and pasting audio clips from previous episodes to do Chef’s voice.
In the end, Chef dies and is resurrected by the Super Adventure Club as Darth Chef, unbeknownst to the town folk who are having a memorial service in his honor. Stan said we shouldn’t remember Chef for what happened in the last week, but for all the good times they had, and not to blame Chef, but for the “fruity little club that scrambled his brains.”
P.S. It’s really interesting to watch a Wikipedia entry in the process of being created.
