Interestingly enough, it is these wacky Europeans who have favored us with South Park Studio (Ver. 2), a South Park character generator. It's a handy-dandy device that uses a simple Flash interface to select various colors and styles of standard South Park body part fare to create your own delightfully profane little ragamuffin. You can even put your character in such famously fictitious locales as "Stark's Pond" or "the bus stop."
Go there now and South Park-ize your friends, family, and favorite member of the Facts of Life cast... (*psssst* Think Tootie!)
