A man goes into a dentist's office.

"How much do you charge for a wisdom tooth to be removed?" he asks the dentist.

The dentist says, "$100 is the standard fee."

"No way!!", says the man, "I'm not paying that much! Can't you do it for less?"

"Well," says the dentist, "If I don't use anesthetic, I could lower the cost to $70."

"That's still too expensive. Can you do anything cheaper?"

"If I don't use any electricity," the dentist replies, "and I just pull it with a pair of pliers, it will only cost $20."

"No, that is still too much money!" said the man.

"Well, I'm sorry!" said the dentist, becoming angry, "What do you want me to do? Do you want me to get a student dentist and let him pull the wisdom tooth as on-the-job training and charge you $5?" yells the dentist.

"That's perfect!" said the man, "Make an appointment for my wife on Monday!"
