Kathy Griffin made four appearances on the American version of Whose Line, playing numerous games, such as Irish Drinking Song, Newsflash, Scenes From A Hat, Two Line Vocabulary, Questions Only, Weird Newscasters, and World's Worst.
Kathy is a solo stand up comedienne of some note whose chief stock in trade is satirizing more famous celebrities usually in a disparaging way. Although she characterizes herself as being on the "D-List" even to the point of having a series on cable entitled "My Life on the D-List" she is probably the most famous person to appear as an irregular cast member who was not designated as some kind of special guest.
Fast-witted, ribald and mercurial, she was called one of the world's funniest women by Drew at the beginning of one of the shows in which she appeared.
