Whose Line Is It Anyway? (1998-2007) Tune into Whose Line Is It Anyway? for improv fun! Drew Carey hosts this goofy and freewheeling show where comedians Ryan Stiles, Colin Mochrie, Wayne Brady, and a fourth guest panelist play unrehearsed games in front of a live audience. Watch Whose Line Is It Anyway? on HBO Max. Image Source: Everett Collection
