"Saturday Night Live" for a Nickelodeon audience. That's the basic premise of "All That," a Saturday night staple on Nick's lineup for a decade. The cast members -- who, like "SNL," changed throughout the seasons as people came and left -- participate in comedy sketches, often featuring recurring characters like Goodburger employee Ed and teenage superhero Superdude. Most episodes have a musical guest with some also featuring a guest host. Coincidentally, original cast member Kenan Thompson eventually went on to star on "SNL" beginning in 2003. Other notable alumni include TV personality-rapper Nick Cannon, actress Amanda Bynes and comedian Gabriel Iglesias.
