An old couple arrived at the doctors with a strange request."We want you to watch us making love,"said the man.Puzzled,he obliged.
When it was over he said,"Well that was pretty good considering your age."
And he charged them the standard fee for the consultation.
This happened week after week.They'd make an appointment,bonk away and pay the bill.
The Doctor was unable to find anything wrong with the way they bonked and finally asked,"What exactly are you trying to find out?"
"Nothing,"sait the old bloke."She's married,so we can't go to her house.I'm married, so we can't go to my mine.They charge you $100 at a decent hotel and even a crappy motel charges $30. So we come here for $18 and get $12 back from Medicare."
