At the Dentist
The pretty young Miss was having a tooth pulled and the dentist gave her the usual "This won't hurt a bit" routine before bending over her with a drill in his hand.
He immediately draw back in complete alarm. "Miss," he said in a barely audible wisper, "You have hold of my testicles!"
"Yes, doc, I know," she smiled, "and we aren't going to hurt each other, are we?"
