A guy falls asleep on the beach for several hours and gets a horrible
sunburn.
He goes to the hospital and is promptly admitted after being diagnosed
with second degree burns. He was already starting to blister and was in
agony.
The doctor prescribed continuous intravenous feeding with saline and
electrolytes, a sedative, and a Viagra pill every four hours.
The nurse, rather astounded, said, "What good will Viagra do him?"
The doctor replied, "It'll keep the sheets off his legs."
