To celebrate South Park's ten-year anniversary, creators Matt Stone and Trey Parker picked their favorite episodes to be released as South Park The Hits: Volume 1 In a press release, Stone and Parker said, "People always ask us, 'What's your favorite episode?' And I say, 'It's so hard. It's like choosing between your children.' But then I would have no problem choosing between my children. It would be the tall, smart one."
