Great fun and an excellent theme – appreciate what you’ve got! Walter Matthau goes through Robert Morse’s gauntlet of adultery tests only to discover he’s already found the perfect woman. Hilarious cameos abound, although the film is more of a series of set pieces than a complete entity. Still, worth a look for it’s disavowal of the 1960’s free love “swinger” mentality in favor of the simplicity of a steady love who just happens to be your wife.
