     Mr. Robinson never went to a dentist, because he was afraid. One day his teeth began hurting badly,

and he had to go to a dentist. The dentist did a lot of work in his mouth for a long time. On the last day Mr.

Robinson said to him,"How much is all this work going to cost?" The dentist said,"Twenty dollars." But he

did not ask him for the money.

     After a month Mr. Robinson phoned the dentist and said,"You haven't asked me for any money for your

work last month."

     "Oh," the dentist answered, "I never ask a gentleman for money."

     "Then how do you live?" Mr. Robinson asked.

     "Most gentlemen pay me quickly," the dentist said, "but some don't. I'll wait for the money for two

months, and I'll say he isn't a gentleman, and I'll ask him for the money."
