A Visit To The Dentist

A man walks into a dentist's surgery.

"How much do you charge for a wisdom tooth to be removed?"

"£90"

"I'm not paying that much! Can't you do it for less?"

"Well...if I don't use anesthetic I could lower it to £70."

"That's still too much."

"OK...if I don't use any electricity and I just pull it with a pair of pliers that'll cost £20."

"Nope - still too much."

"Right, I suppose I could get a student in - he could do it with no anesthetic and with pliers and that will only be £5."

"Brilliant! Book the wife in for Monday!"
