Hoping to break the monotony of her domestic existence, Samantha dons a black wig. At the same time, Darrin suggests that he and Sam "get away from it all" by checking into a downtown hotel suite. Inevitably, they are spotted by Larry Tate, who, failing to recognize the bewigged Sam, is convinced that Darrin is a philanderer. Written by Bernard Slade (who, coincidentally, later wrote the hit "infidelity" stage comedy Same Time, Next Year), "That Was My Wife" first aired on April 29, 1965. ~ Hal Erickson, Rovi
