Cartman, Stan, Kyle and Kenny play World of WarCraft too. The popular MMP was featured on the season premiere of South Park.
|A great evil has been thwarted, thanks to the courage and determination of four brave heroes. In the darkest hour, South Park's Cartman, Stan, Kyle, and Kenny answered the desperate cries for help of millions of players and defeated, nay, pwned the evil griefer who had been terrorizing players all over Azeroth. Our eternal gratitude goes out to the champions of South Park; may their names forever be remembered amongst the heroes and legends of Warcraft.|
