The doctor asked, "What can I do for you?"

The man said, "Will you watch us have sexual intercourse?"

The doctor looked puzzled but agreed. When the couple had finished, the doctor said, "There is nothing wrong with the way you have intercourse," and he charged them $32.00 for the office visit.

This happened several weeks in a row. The couple would make an appointment, have intercourse, pay the doctor and leave.

Finally the doctor asked, "Just exactly what are you trying to find out?"

The old man replied, "We're not trying to find out anything. She is married and we can't go to her house. I am married so we can't go to my house. The Holiday Inn charges $60.00. The Hilton charges $98.00, we do it here for $32.00, and I get back $28.00 from Medicare for a visit to the doctor's office."
