The Towel

An elderly man went to the Doctors. He explained to the Doctor that he has a young wife, and although they were sexually active together, his wife had never had an orgasm, no matter what they tried, and he was worried that she might leave him because of this.
The Doctor said ' Get a young, well-endowed man, have him stand in front of your wife when you are making love, ensuring that she can see his manhood, and have him waving a towel over you. That should do the trick'.
So the elderly man tried this, but still his wife didn't orgasm. Back to the Doctors he went.
'Next time,' said the Doctor, 'have the young man make love to your wife while YOU wave the towel, that should do the trick'.
So the elderly man tried this, and sure enough, his wife had a screaming, creaming orgasm.
After they had finished, the elderly man tapped the young man on the shoulder and said.....




'That's how to wave a f*****g towel, sonny!!!'
