A guy fell asleep on the beach for several hours and got a horrible sunburn, specifically to his upper legs. He went to the hospital and was promptly admitted after being diagnosed with second-degree burns.

With his skin already starting to blister, and the severe pain he was in, the doctor prescribed continuous intravenous feeding with saline, electrolytes, a sedative, and a Viagra pill every four hours.

The nurse, who was rather astounded, asked, "What good will Viagra do for him, Doctor?"

The doctor replied, "It won't do anything for his condition, but it'll keep the sheets off his legs."

In Denmark, in retirement homes, they have started to administer ½ a Viagra in the evening so the old men dont rool out of bed at night, and ½ in the morning so they dont piss their slippers.

^^^^ I do that now , and I dont live in a retirement village ;-)
