A guy and a girl met at a bar. They started getting along really well they
decide to go to the girl's place for a drink.

A few drinks later, the guy took off his shirt and washed his hands.

He then took off his socks and washed his hands.

The girl looked at him and said, "You must be a dentist!"

Flabbergasted, the guy responded, "Yes. That's amazing. How did you figure that
out?"

The girl said, "Easy... You keep washing your hands."

One thing led to another. They migrated to the bed and things became more
passionate. After they were done, the girl said, "You must be a GREAT dentist!"

The guy was very very surprised, and said, "Yes, I sure am a great dentist...
How did you figure that out?"

The girl said, "Easy... I didn't feel a thing."
