S1, E12: Running from 1994 to 2005, Nickelodeon's sketch-comedy series "All That" spawned the popular spinoffs "Kenan & Kel," "The Amanda Show" and "The Nick Cannon Show." The groundbreaking show gets a reboot for a new generation of kids, but the premise remains the same: take talented youngsters with serious comedy chops and set them loose in front of a live studio audience, along with performances from hot musical artists and surprise guests from the worlds of TV, film and comedy. Who knows: the next Kenan Thompson and Kel Mitchell (original cast members now executive producing the new incarnation) may just be lurking among this fresh batch of wacky entertainers.
