Carol Burnett: Climbing the Hollywood sign, getting her first laugh & having fun at 90

Carol Burnett is one of the most adored comedians of all time. In 1967, she broke up the boys club that was network television with her freewheeling variety hour, “The Carol Burnett Show.” Now, more than half a century later, she’s still flexing her quick wit and comedic acting skills on shows like “Better Call Saul” and “Palm Royale.” In this special interview from Los Angeles, Carol sits down with Tom to reminisce about the hard-won lessons and chance encounters that helped her become a star.
