A guy and a girl meet at a bar. They get along so well that they
decide to go to the girl's place.

A few drinks later, the guy takes off his shirt and then washes his
hands. He then takes off his trousers and washes his hands again.

The girl has been watching him and says, "You must be a dentist."

The guy, surprised, says "Yes....how did you figure that out?"


"Easy," she replied, "you keep washing your hands."


One thing led to another and they make love. After they are done, the
girl says, "You must be a really good dentist."


The guy, now with a boosted ego says "Sure, I'm a good dentist, how
did you figure that out?"


She replies "Didn't feel a thing."
