One night, as a couple lies down for bed, the husband gently taps his wife on the shoulder and starts rubbing her arm.
The wife turns over and says, "I'm sorry, honey, I've got a gynecologist appointment tomorrow and I want to stay fresh."
The husband, rejected, turns over and tries to sleep. A few minutes later, he rolls back over and taps his wife again.
This time he whispers in her ear, "Do you have a dentist appointment tomorrow, too?"
