A couple, both age 67, went to a sex therapist's office. The doctor asked, "What can I do for You?" the man answered, "Will you watch us have sex?" The doctor looked puzzled, but agreed. When the couple finished, the doctor said, "There's nothing wrong with the way you have intercourse," and charged them $32. This happened several weeks in a row. The couple would make an appointment, come to the doctor's office, have sex with no problems, pay the doctor, and then leave.
Finally, one day, the doctor asked, "Just exactly what are you trying to find out?" The old man said, "We're not trying to find out anything. She's married and we can't go to her house. I'm married and we can't go to my house. The Holiday Inn charges $60. The Hilton charges $78. We do it here for $32, and I get $28 back from Medicare."
