This show is often remembered for an incident in which Johnny Carson interrupted a taping session. During an appearance on The Tonight Show Starring Johnny Carson (1962) with guest host Bob Newhart, Don Rickles accidentally broke the cigarette box on Carson's desk. When Carson returned to the show the next day, he discovered the broken box during taping. Carson took the broken box and a cameraman with him to the adjacent studio where Rickles' show was taped and teased him. This incident was played on Carson's annual specials and also on The Tonight Show with Jay Leno (1992) on the day Carson died.
