Sunburn
A man was on holiday in the Caribbean and liking the continual good weather settled down for a day's sunbathing.
He fell asleep and after a whole day his legs were sunburnt beyond belief and he could hardly stand for the pain.
So he goes along to the doctor for treatment.
The doctor looks at his sunburnt legs and said, "well, you realize that this is only a small village surgery and in reality I've really got nothing at all to help you." "However, try this and gives him one tablet of Viagra."
So the man says "but I've got acute sunburn what's a Viagra tablet going to do?"
The doctor says, "basically, nothing at all for the sunburn but it will help keep the sheets off of your legs tonight."
