Carey, Ryan Stiles (The Drew Carey Show), Colin Mochrie and a rotating roster of actor/comedians improvise their way through the half-hour of non-stop laughs. Other performers include Wayne Brady, Greg Proops and Brad Sherwood. Multi-talented musician Laura Hall is on hand to provide a variety of musical cues often used in a sketch (e.g. an improvised song about plumbers is sung to a reggae beat).
Whose Line Is It Anyway? premiered on August 5, 1998.
