This guy wakes up out of a deep sleep and, feeling real horny, nudges his wife awake and asks, "Why don't we , eh?" She replies, "I have an appointment at the gynecologist tomorrow and you know I don't like to make love the night before." So the husband agrees and rolled back over and started to go back to sleep.

A few minutes later, he nudges his wife again and asks, "You don't by any chance have a dentist's appointment tomorrow, do you?"
