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 in the emergency room with second-degree burns. He was already starting to blister and in agony. The doctor prescribed continuous intravenous feeding with saline and a sedative and a Viagra pill every four hours. The nurse, rather astounded, said, "What good will Viagra do him?" The doctor replied, "It will keep the sheets off his legs."
