Whose Line Is It Anyway? Show Summary

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.
