A man goes into the dentist's office to get a bad tooth pulled. As he opening his mouth and the dentist is about to drill, he asks how long the procedure will take.
"Five minutes," the dentist proudly states. "You'll be out of here before you know it, and won't feel a thing - the local will last 10 minutes."
"And how much is this costing again?" the man asks.
"$190" the dentist states plainly.
"Geesh," the man grumbled, "it's a crime to be able to hold a man captive for five minutes and charge him $190!"
"Then for you, I'll give you a special!" the dentist said, and the man's face looked pleasantly relieved. "I'll take 15 minutes to do the extraction."
