An old man brought his wife with him to his dentist appointment.

When the nurse called his name, the wife stood up, walked into the room, sat in the dental chair, dropped her underwear, and spread her legs.

The dentist, a little taken aback, blinked and said, "Ma'am… I'm a dentist, not a gynecologist."

She replied, "I know. We just need my husband’s teeth back."
