A man and a woman meet at a bar. They get along so well that they decide to go to the woman's place.
A few drinks later, the man takes off his shirt and then washes his hands.
He then takes of his trousers and washes his hands again.
The woman has been watching him and says, "You must be a dentist."
The man, surprised, says "Yes! How did you figure that out?"
"Easy," she replies, "you keep washing your hands."
One thing leads to another and they make love.
After they are done, the woman says, "You must be a good dentist."
The man, now with a boosted ego says, "Sure, I'm a good dentist. How did you figure that out?"
"Didn't feel a thing!"
