Scotsman at the expensive dentist

A Scotsman goes to the dentist and asks how much it is for an extraction.

"85 pounds for an extraction sir" was the dentists reply.

"Och! huv ye nay got unythin cheaper", replies the Scotsman getting agitated.

"But that's the normal charge for an extraction sir", said the dentist.

"What aboot if ye didnae use uny anaesthetic?", 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 pounds", said the dentist.

"Hmmmm, what aboot if ye used one of ye dentist trainees and still wi' oot anaesthetic", said the Scotsman.

"Well it's possible but they are only training and I can't guarantee their level of professionalism, and it'll be a lot more painful, but I suppose in that case we can bring the price down to say 40 pounds", said the dentist.

"Och that's still a bit much, how aboot if ye make it a training session and have yon student 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 pounds in that case", said the dentist.

"Wonderful, it's a deal" said the Scotsman ... "Can ye book me wife for next Tuesday?"
