Excuses Excuses

One night, a man rolls over in bed and gives his wife a big, knowing grin. Immediately realising his intentions she says,

"Not tonight darling. I have an appointment with the gynaecologist tomorrow morning and I want to stay fresh and clean."

Dejected and disappointed, the man rolls over and tries to get to sleep. A few minutes later he rolls over and prods his wife again.

"Tell me, do you have a dentist appointment tomorrow, too?"
