One evening a man drove his secretary home after she had worked late at the office and wasn't feeling well enough to drive herself. Although this was an innocent gesture, he decided not to mention it to his wife, who tended to get jealous easily.

Later that night the man and his wife were driving to a restaurant. Suddenly he looked down and spotted a high-heeled shoe half hidden under the passenger seat.

Not wanting to be conspicuous, he waited until his wife was looking out her window before he scooped up the shoe and tossed it out of the car. With a sigh of relief, he pulled into the restaurant parking lot.

That's when he noticed his wife squirming around in her seat. "Honey," she asked, "have you seen my other shoe?"
