Sunburn
A man was on holiday in the Caribbean and, liking the warm tropical
weather, settled down for a day's sunbathing. He fell asleep, and
after a whole day his legs became sunburnt beyond belief. He could
hardly stand the pain. He decided to go to the doctor for treatment.
The doctor looked at his lobster-colored legs and shook his head. "You
must realize that this is only a small village surgery," he explained.
"I've really got nothing at all to help you. However, try taking this
just before bedtime..." The doctor gave him one tablet of Viagra.
Puzzled, the man asked, "I've got acute sunburn: what's a Viagra
tablet going to do?"
"Nothing at all for the sunburn,the doctor replied, "but it will keep
the sheets off your legs"
