Just now heard Johnny Carson tell this on a rerun show from many years ago: hope it passes muster-
A woman rushes into her dentist's clinic, holding her jaw, obviously in distress. He tells her.."open wide, let's take a look at this molar."
But she interrupts him saying, " I think I would rather have a baby than to endure the pain from my tooth extraction, doctor."
To which he replies "Please make up your mind lady. I have to adjust the chair!"
