I found this on Facebook and thought of you lot.
A guy fell asleep on the beach and got a horrible sunburn, specifically to his thighs. He went to the hospital and was admitted with second-degree burns. His skin was starting to blister and he was in severe pain so the doctor prescribed continuous saline, electrolytes, a sedative, and a Viagra pill every four hours.
The nurse, who was astounded, asked, 'What good will Viagra do for him'
The doctor replied, 'It won't do anything for his condition, but it'll keep the sheets off his legs.
Oh, dear. It shouldn't be, but that is a really good joke.
