WITH GUEST STAR APPEARANCE BY DARREN CRISS ("HOLLYWOOD") - Hosted by comedian Aisha Tyler, cast members Wayne Brady and Colin Mochrie, along with guest comedians Jeff Davis and 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.
