A guy went to see a private dentist and ask him how much he
charges for a tooth extraction. The dentist replied, "that will
cost you $120 dollars"
Guy: Can you do it cheaper?
Dentist: Well, I think I can reduce it to $100 for you if I don't
use painkillers
Guy: That is still too expensive, can you make it cheaper
still?
Dentist: Well, I can charge you $60 if I do it manually without any
instruments, it will be helluva pain but well, it works
Guy: That is still too expensive, I don't earn much, can you reduce
it more?
Dentist: Okay, $40 if you let my junior dentist do it for you
Guy: Hmmm... that's still costly... can you do more to help?
Dentist: My student can do it for you for only $20
Guy: What if you turn this tooth extraction session into a class?
Will you charge cheaper?
Dentist: Okay, my last deal will be $5, I will turn this session
into a class of 50 students, the student will be doing it, without
instrument, that means manual extraction and without painkillers.
So, when do you want it?
Guy: That's wonderful... oh it's not me, it's for my wife... how
about tomorrow?
