An elderly couple, in their 80's, went to a sex therapist's office and asks the doctor to watch them have sex. The doc is so amazed at such an elderly couple wanting sexual advice that he agrees. After watching them, the doc says, "There is absolutely nothing wrong with the way you have sex." He charges them $50 and they go on their way. The couple returns the next week and again ask the doc to watch them have sex. After several weeks of this, the doc finally asked the couple what they wanted him to find out. The old man replies, "we're not trying to find out anything. I'm married, so we can't go to my house, she's married so we can't go to her house. The Holiday Inn charges $98, the Hilton charges $139. We do it here for $50 and Medicare pays $43 of it, leaving me only $7 to pay to get some ass, & since ur a doctor it's confidential =))
