S15 E2: Guest star TINASHE sings for your enjoyment. Hosted by comedian Aisha Tyler, WHOSE LINE IS IT ANYWAY? features cast members Ryan Stiles, Wayne Brady and Colin Mochrie, along with guest comedian JEFF DAVIS 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 conjure up hilarious characters, scenes and songs out of thin air. After each round of improvisation, Aisha will dole out points to our four performers and declare a winner at the end of every episode.
