This year's special, taped at the Kennedy Center for the Performing Arts, honors Bill Cosby with the Mark Twain Prize for American Humor. A stellar list of entertainers honors Cosby, a man who has dominated the field of comedy for 40 years. The routines that Cosby performed on his best-selling records in the 60's are still remembered word for word today. His pioneering television programs were huge hits, season after season. His live performances sell out to this day. As a comic writer, actor, live performer and commentator, Cosby has been the gold standard for 40 years. And his special rapport with children has graced everything from PBS children's shows to Jello commercials.
