'Terrance and Phillip in Not Without my Anus'

The airdate: April 1, 1998 The shock: Parker and Stone promised to reveal the identity of Cartman's father in the second season premiere. But as an April Fool's gag, they instead aired an episode that had nothing to do with anyone in South Park. Instead, it focused on the cartoon characters Terrance and Phillip. The reaction: Fans were not amused by the switcheroo and made their displeasure known to Comedy Central. As a result, the follow-up episode, which was originally scheduled to air in May, was pushed up to air the following week.
