If at first you don't succeed... (15)
One night, as a couple lays down for bed, the husband starts rubbing his wife's 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.
A few minutes later, he rolls back over and taps his wife again.
"Do you have a dentist appointment tomorrow too?"
