Mark goes to see dentist and asks "How much to pull two wisdom teeth?"
Dentist says "$100.00."
Mark says, "too much. Can't you do it for less?"
Dentist says "I can do it for $50 if I cut out the novacaine."
Mark says, "that's better but still too much. Can't we do it any cheaper?"
Dentist says, "I could let my trainee do it for $20 but she has never pulled a tooth before and it would be quite painful."
Mark says, "That's great. Schedule my friend Joe for next Tuesday."
