Nurse

A patient is lying in bed in the hospital with an oxygen mask over his mouth and nose and still heavily sedated from a four hour operation.
A cute young nurse appears to sponge his hands and face. ”nurse" he mumbles from behind the mask, "are my testicles black?" embarrassed, the young nurse blushes and replies, "I don’t know. I’m only here to wash your hands and face." he struggles again to ask, "nurse are my testicles black?"
Finally, she pulls back the covers, raises his gown, holds his privates and jiggles them about a bit, takes a good look and says, "there’s nothing wrong with them!" The man pulls off his oxygen mask, and says very slowly, "that was very nice but listen very, very carefully - ARE....MY.....TEST....RESULTS....BACK?"
