A man fell asleep on the beach under the noon day sun and suffered a severe sunburn to his legs and was taken to the hospital.

His skin had turned a bright red and was very painful and had started to blister.

Anything that touched his legs caused agony.

The doctor prescribed continued intravenous feedings of water and electrolytes, a mild sedative and Viagra.

Rather astounded, the nurse inquired, "What good will Viagra do him in that condition?"

The doctor replied, "It will keep the sheet off of his legs."
