Thank your lucky shoes

A man drove his secretary home after she had a little too much to drink at a
party.  Although nothing happened, he decided not to mention it to his wife.

Later that night, the man and his wife were in the car when he spotted a high-heeled shoe under the passenger seat.  While his wife wasn't looking, he picked up the shoe and tossed it out of his window. Later, as they got out of the car, his wife asked, "Honey, have you seen my other shoe?"
