FIFI BLOWS HER TOP (1958)

The stooges reminisce about their wartime romances in Europe. After they finish their tales, they discover that Joe's girl Fifi, whom he left behind in Paris, has moved in next door. The only problem is that she's now married, with a very jealous husband. The husband turns out to be a real cad, and when Fifi overhears him tell about his plans to find a new wife, she clobbers him and goes back to Joe.
