A sort-of Saturday Night Live for the preteen set, Nickelodeon 's All That features a blend of comedy skits, musical guest performances, and kid-friendly guest stars. Following in the footsteps of its adult inspiration, the series spawned a movie from one its sketches (Good Burger) and served as a career launching pad for several of its cast members, including Amanda Bynes, Nick Cannon, and Kenan Thompson who, appropriately enough, joined the cast of SNL in 2003. ~ Skyler Miller, Rovi
