Another hilarious episode that Matt Stone and Trey Parker (the creators of south park) came up with was the one were the boys all buy ninja weapon and they are all fighting each other and then butters goes to fight them as profesor chaos but he gets a chinese throwing star stuck in his eye. Then the boys try to get him to the hospital and so they wont get him in trouble they dress him up like a dog but then he runs away and the pound catches. This episode is hilarious.
