The dentist told her that the tooth was decayed and would have to come out.
After the tooth had been removed, the dentist said to the young mother, “I am sorry madam, but I shall have to charge you $100 for pulling your boy’s tooth”.
“A hundred dollars!”, the young mother responded in shock. “Why do I have to pay $100? I understood you to say that you charged only $20 dollars for taking a tooth out!”
“Yes that’s correct” replied the dentist, “but your boy yelled so terribly that he scared four other patients out of the office!”
