Via Vodkapundit:
A guy falls asleep on the beach for several hours and gets 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 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."
