Ross, better known as ‘Roastmaster General,’ has been on the comedy scene for years and is referred to as “an heir” apparent to old school comic masters as Buddy Hackett and Rodney Dangerfield.” He most recently got major laughs at the roast of newly minted ‘Dancing with the Stars’ contestant, David Hasselhoff.
