A boy and his mother stood in the dentist's office, looking at a display case. "If I had to have false teeth, mother, I'd take that pair there," said the small boy, pointing.
"Hush, Willie," interrupted the mother quickly, "Haven't I told you it's bad manners to pick your teeth in public?"
A dentist, after completing work on a patient, came to him begging for a favor.
Dentist: Could you help me out? Could you give me a few of your loudest, most painful screams?
Patient: Why? Doctor, it wasn't at all bad this time.
Dentist: There are so many people in the waiting room right now, and I don't want to miss the four o'clock ball game.
