Wife's Appointment

One night, as a couple lay 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 gynaecologist 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?"
