Chris Rock and Jay Leno guest star, as Bernie takes a long-standing grudge against Rock all the way to The Tonight Show. Upset after seeing Rock get preferential treatment at a doctor's office, Bernie's blood boils even more when his poker buddies fall all over his fellow comic, who drops by to tell Bernie that they will be co-hosting an awards show. That's not cool with Bernie, who maintains that back in their early days as stand-ups, Chris once told a joke on stage that Bernie had told him just moments before. The situation comes to a head when they're booked on Leno, who's unaware of the rift between the two. (thetvdb.com)
