An older couple goes to a doctor's office and ask him to watch them have sex. Although he considers it a rather bizarre request, the doctor agrees and watches them have sex.
After it was over, the doctor tells them he noted nothing abnormal. The couple thanked him while dressing and paid the receptionist for the visit. Every week for three weeks, the couple returned with the same request, which the doctor obliged.
However, by the last visit, the doctor asked the couple what the deal was. The old man explained, "Well, my kids still live at my place so we can't go there. She has grandchildren at her place so we can't go there. A hotel room costs $40 and you only charge us $35 -- and medicare picks up 80 percent of that."
