Sacha Baron Cohen is an over-the-top comedian who, rarely out of character in public, will do just about anything for a laugh (or a film.) Interview heads of state as faux political reporter Borat Sagdiyev? Sure. Pose naked on the cover of "GQ"? No problem. We take you through the many faces of the British funny man.
Here, Cohen appeared on the "Late Show with David Letterman" on July 7, 2009 in New York.
