Hosted by comedian Aisha Tyler, cast members Ryan Stiles, Wayne Brady and Colin Mochrie, along with guest comedian Greg Proops, put their comedic skills to the test through a series of spontaneous improv games that are prompted only by random ideas supplied by the studio audience. The four performers must use the little information they have and their wild imaginations to depict different characters and an array of scenes, as well as perform songs. After each round of improvisation, Aisha will dole out points to our four performers and declare a winner at the end of every episode.
Whose Line Is It Anyway? (1998-2004, 2013 - ?) is a continuation of the British show of the same name which aired from 1988 to 1998 with many of the same performers.
It features some of the nation's finest improvisational comedians, including Florida's Wayne Brady, Canada's Colin Mochrie, and Ryan Stiles and Drew Carey from The Drew Carey Show.
Each week, the preceding four and a rotating group of actors and actresses spontaneously played games with outrageous scenes, weird quirks, or (sometimes off-key) songs.
