A couple, aged 65 and 67, went to the doctor's office. The Doctor asked them, "What can I do for you?" The man said, "Will you watch us have sexual intercourse?" The doctor looked confused but agreed. When the couple had finished, the doctor said, "There is nothing wrong with the way you have intercourse." And he>charged them $20.00 . This happened several weeks in a row. The couple would make an appointment, have intercourse, pay the doctor and leave. Finally the doctor asked, "Please explain, just exactly what are you trying to find out?" The old man responded, "We're not trying to find out anything. She is married and we can't go to her house. I am married and we can't go to my house. The Sheraton Hotel charges $52.00 and Hilton Hotel charges $37.00. We do it here for $20.00 and I get $18.00 back from from insurance company for a visit to the doctors office.
