All That is back! '90s babies rejoice, the sketch show ran on Nickelodeon from 1994 to 2005, is having a reunion. All That brought us talented actors like Nick Cannon and Kenan Thompson, plus awesome musical guests like Aaliyah, Brandy and Usher. Until the reunion comes to The Splat this April, we revist some of our favorite cast members--then and now. Click on the photos -- and let the nostalgia begin!
