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, but I've got a gynecologist’s 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's appointment tomorrow too?'
