A Scotsman asks the dentist the cost for a tooth extraction.

"85 pounds for an extraction sir," was the dentist's reply.

"85!!! Huv ye no' got anythin' cheaper?"

"That's the normal charge," said the dentist.

"Whit aboot if ye didnae use any anesthetic?"

"That's unusual, sir, but I could do it and knock 15 off."

"Whit aboot if ye used one of your dentist trainees and still without an anesthetic?"

"I can't guarantee their professionalism and it'll be painful. But the price could drop to 40."

"How aboot if ye make it a trainin' session, ave yer student do the extraction with the other students watchin' and learnin?"

"It'll be good for the students," mulled the dentist. "I'll charge you 5. But it will be traumatic."

"Och now yer talkin' laddie! It's a deal," said the Scotsman.

"Can ye confirm an appointment for the wife next Tuesday then?"
