An very elderly couple turn up at the doctors.
So how can I help? the docor asks.
Well it's about our sex lives the old geezer coughs up.
"I see", the doctor says, "and what seems to be the problem?"
"Well what we'd really like" the old dear says taking over, "is for you to watch us make love, and tell us if there's anything wrong".
"You want me to watch you making love?Right here?In my surgery?"asks the disguisted doc.
"That's right" says the old boy with a grin.
"Well there are people who are in a far better position to assist" starts the doctor, "perhaps if I can refare you.........:
"Oh please" cries the old lady, "we're really desperate".
"Come on mate" the old bloke says."Look, just give us one week to see if you can work the problem out.I'll even throw a fiver a day in for the inconvieniance".
"Well, I don't know...."says the doc.
"All right, ten pounds every day, that's fifty quid from Monday to Friday".
"Well alright then, says the doctor".
"GREAT" yells the old chap."Come on Gladys, get your girdle off girl".
"Whatever you say Ernie" the old girl says with a grin.
"You mean your going to start now?" the doctor asks.
"No time like the present" Ernie says rubbing his hands together.
For the next half an hour, the doctor is forced to watch this very old couple in a variety of positions while making notes.
"So how'd you think I did?" asks Ernie with a grin at the close of the days proceedings.
"Well I couldn't see any problem" the doctor says, trying to hold his dinner in.
"Just wait and see what happens tomorrow" says Gladys.
For the next week, the doctor is subjected to this (for him) very unpleasant routine.THe couple come in, immediatly undress, and go for it

.Every day, the doctor fails to see anything particulary wrong.
On the final day, the doctor, as usual, gives them a perfect bill of health.
He then notices that Ernie is having a very hard time trying to keep a straight face.
"Well we're off, thanks for everything" calls Gladys.
His suspicions aroused, he pulls Ernie to one side as Gladys leavs the room.
OK, what's the gag?, the doc asks.
"Well, it's like this" Ernie starts."See it's cold as a fridge at my place, her husband is always at home, and at 10 pound a day, your still cheaper than a hotel
