They sort of were once. In the episode where Cartman wanted to form a Christian rock group and have a platinum selling album (because it was easier to write songs for -- just replace words like "baby" and stuff like that with "Jesus" in songs that already existed). Kyle said "Dude, that'll never work." and Cartman replys with "Why not? It worked for Creed." He also had a $5 bet with Kyle that his band (Faith +1) could make a platinum selling album. The joke was on Cartman when he found out after selling a million albums that in the Christian rock industry, the albums go Gold, then Frankensence, then Myrrh. So he didn't sell platinum, only Myrrh, and he owed Kyle the 5 bucks.
Anyway, back to the topic. I haven't seen any SPC's of Creed. if you go to
www.southparkstudios.com, there is a thing you can open to create a South Park character. Then you can try to make your own with the things they give you.
