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. With his skin already starting to blister, and seeing
the
severe pain he is in, the doctor prescribes an IV with saline, electrolytes,
a sedative, and a Viagra pill every four hours.
The nurse, who is rather astounded, asks, "What good will Viagra do,
Doctor?"
The doctor replies "It'll keep the sheets off his legs."
