Nurse walks into a hospital room, and the patient, wearing an oxygen mask, looks at her and asks "Are my testicles black?" The nurse is flustered. "Excuse me?" "Are my testicles black?" he says again. The nurse blushes and figures that she might as well check and put the man's mind at ease....so she lifts up the bedsheet, lifts up his hospital gown, and takes a peek. "Everything looks fine, sir. There is no discoloration of any kind on your testicles." The man's face turns to shock and anger, "NO!" he says as he rips off the oxygen mask. "I was asking you if my test results were back!"
