A dentist had an old lady patient who was very hard to handle. As soon as she sat in the chair, she panicked and would clamp her mouth shut so firmly that he couldn't get it open to work on her teeth.

One afternoon, on about the third try to treat the old lady, the dentist figured out a way to get the job done. He excused himself from the old lady, went back to the reception desk and told his receptionist that as soon as he was ready to work on the old lady's teeth, she was to move up behind her and jab her in the rear with a long pin. Well the receptionist did what she was told, and sure enough, the old lady opened her mouth to holler and that opening, maintained with a pry to keep it that way, got the job done.

Finally finishing with his work, the dentist said, "Well now, that wasn't so bad, was it?"

"Nope, not so bad," said the old lady. "But I'll tell you this, I never expected to feel the pain of a toothache way down in my ass."
