Swing Shift Cinderella by Tex Avery
A married man approaches a woman in the supermarket and says: “I have lost my wife in the corridors… Do you mind talking to me for a while?”.
She asks him: “Wouldn’t it be better to look for her instead of to talking to me?”
And the married man answers her: “That wouldn’t be necessary… every time I talk to a beautiful woman, my wife appears out of nowhere…!”.
