Paar's primetime show aired for three years, including a wide variety of guests such as comedian Brother Dave Gardner, actor-director Peter Ustinov, Lawrence of Arabia's brother, actor Richard Burton, pianist-actor Oscar Levant, news icon Lowell Thomas, boxing champion Muhammad Ali reciting his poetry to piano accompaniment by Liberace, Judy Garland, Jonathan Winters, Woody Allen, Bill Cosby (whose nickname for Paar was "The Boss"), Bette Davis, Robert Morley, Cliff Arquette (as his Charley Weaver character), Dick Gregory, and many others. The final segment of the series, broadcast on June 25, 1965, featured Paar sitting alone on a stool, sharing a discussion that he had with his daughter Randy, who called Paar's departure a sabbatical. He said that his own field was, though not completely used up, "a little dry recently." Then he called to his German Shepherd, which came to him from the seats of what was, for once, an empty studio, and walked out. (Johnny Carson used the same format, "sans" dog, for his own farewell episode of "The Tonight Show" in 1992.)
