Saw this in a newsletter:

A man passed out on the beach in San Diego for four hours (couldn’t have been in June) and got a horrible sunburn, especially to the front of his legs above the knees.  He was taken to the hospital by worried friends.  He was admitted to the hospital after being diagnosed with second degree burns.  The patient was in severe pain and the skin was already blistering.  The doctor prescribed IV saline, electrolytes, a sedative and pain medicine.  He surprised the nurse by telling her to give the patient a Viagra pill every four hours.

The nurse asked, “What is the purpose of the Viagra, Doctor?”

The doctor replied, “It won’t do anything for his condition, but it will keep the sheets off his legs.”
