A husband of beautiful wife phones a dentist to enquire about the cost for a tooth extraction.
"Rs.850 for an extraction, sir" the dentist replied.
"Rs.850!!! Don't you have anything cheaper?"
"That's the normal charge," said the dentist.
"What about if you just don't use any anaesthetic?"
"That's unusual, sir, but I could do it and knock Rs.150 off.
"What about if you just use one of your dentist trainees and still without anaesthetic?"
"I can't guarantee their professionalism and it'll be painful. But the price could drop to Rs.400".
"How about if you make it a training' session, and one of your students do the extraction while the other students watch and learn?"
"It'll be good for the students", mulled the dentist. "and it's going to be very traumatic, but I'll charge you Rs.50.
"Now you talking ! It's a deal," said the Husband "Can I confirm an appointment for my wife for tomorrow then?"
