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 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?"
