Funny Jokes

My father was in the dentist's chair having a root canal done. Every so often, the dentist would stick a large toothpick-like object into the tooth's canal to see how far he had drilled. Each time, this thing caused my father great pain, but whenever he complained, the dentist replied, "Oh, that doesn't hurt -- it's just a measuring device.
This happened a couple more times. Again my father complained -- again he got the same response. Finally my father sat up in the chair, took all the stuff out of his mouth and looked straight at the dentist. "Excuse me for a moment," Dad said. "I have to go out to my truck, get my tape measure and whack you in the head with it. It shouldn't hurt, though. It's just a measuring device."
