A guy & 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 good dentist."

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

"Didn't feel a thing!"

Ah that was funny I used to work for a dentist and I can defintiely see someone saying that to him! On a side note - are you aware that cavities are transmittable? Thats right boys and girls you can catch your fellow spit swappers cavity- it is just like a virus! So - be careful who you swap spit with - I usually ask when the last check up was and if they had thier cavities filled

Ouch, that had to hurt!
