A man fell asleep on the beach and burned so badly he was hospitalized with severe second degree burns.

The doctor was setting up the treatment schedule with the nurse.

"We will need to change the dressings hourly and wash the blisters with chilled distilled water," the doctor instructed, "and give him a Viagra every four hours."

"Doctor? A Viagra? Will that help the burns?" asked the nurse.

"Not really, but it will keep the sheets off his legs."
