An attractive woman is enjoying her conversation with a man at a bar, and they decide to go home.
As they’re getting ready for bed, the woman notices that after the man removes his socks, he washes his hands. The same thing after his underpants come off.
“You must be a dentist,” she said.
“How could you tell,? “ he said.
“The repetitive hand washing,” she said.
After they were finished, and lying there, she said, “You must be a great dentist.”
He said, “Yeah, I don’t want to boast, but I’ve heard that before. But how could you tell?”
“I didn’t feel a thing,” she said.
