You cannot not love South Park! They are so deliciously outrageous that you just can't wait for the next episode to come out. And on top of it all, they are the first show in the world that made all their episodes free for viewing on their official web page!
I loved the way they did the show in the beginning, with the characters like the devil and Sadam and those annoying Canadians Terence and Philip, but I love the way they do it today as well - more down to Earth and in touch with real life situations. Man, Trey and Matt are geniuses and that's that!
