A couple, both 67, went to a sex therapist's office.

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. The doctor examined them and then directed them to disrobe and go at it.

When the couple finished, the doctor reexamined them and, upon completion, advised the couple, "There's nothing wrong with the way you have intercourse." He then charged them $32.
