Ever The Opportunist

One night a couple was lying in bed. The husband was feeling frisky so he rolled over and tapped his wife on the shoulder and started rubbing her arm. The wife turns over and says "I'm sorry honey, but I have a gynaecologist appointment tomorrow and I want to stay fresh."
Rejected, the husband turns over and tries to sleep. A few minutes later he rolls over and whispers in her ear "Do you have a dentist appointment, too?"
