Comedy Central's Page has a whole area about SP. It includes some cool games that relate to the show, especially one called "Cartman" which is like a version of Pac-man except he gets the weight gainer 4000 which makes him go faster and he says stuff like "Kick Ass" and other Cartman phrases.
If you haven't been there, go check it out. They also have a puzzle and when you solve it the character says a phrase...I won't give it away!
