A Scotsman goes to the dentist and asks how much it is for a tooth extraction.
"$85. for an extraction sir", was the dentist's reply.
"Och, huv ye no got enythin' cheaper", replies the Scotsman a bit agitated.
"But that's the normal charge for an extraction sir", says the dentist.
"What about if ye dinna use any anesthetic?" asked the Scotsman hopefully.
"Well it's highly unusual sir, but if that's what you want, I suppose I can do it for $70." said the dentist.
"Hmmmm, what about if ye used one of your dentist trainees and still without anesthetic", said the Scotsman
"Well it's possible but they are only in training and I can't guarantee their level of professionalism and it'll be a lot more painful.
I suppose in that case we can bring the price down to say $40." says the dentist.
"Och, that's still a bit much, how about if ye make it a trainin' session and have yer trainee do the extraction and the other students watchin' and learnin", said the Scotsman hopefully.
"Hmmmmm, well OK it'll be good for the students, I suppose. I'll charge you only $5. in that case", says the dentist.
"Och, now yer talkin' laddie! It's a deal", said the Scotsman. "Can ye confirm an appointment for the wife next Tuesday?"
