 Robert Morse convinces his best friend Walter Matthau that he should fool around with other women in order to preserve his happy marriage. Morse illustrates his point with a series of vignettes acted out by a lot of famous celebrities. Among them are Jayne Mansfield, Lucille Ball, Art Carney, Jack Benny, Carl Reiner, Wally Cox, Polly Bergen, Marty Ingels, Joey Bishop, Terry-Thomas, Phil Silvers, Ben Blue, Hal March, Sam Jaffe and Jeffrey Hunter. The joke of it all is that Matthau is married to lovely Inger Stevens! Title song sung by the Turtles with music by John(ny) Williams.
