A man is lying in bed in hospital with an oxygen mask over his mouth. A young student nurse appears to sponge his hands and feet.

"Nurse", he mumbles from behind the mask, "Are my testicles black?"

Embarrassed, the young student replies, "I don't know I'm only here to wash your hands and feet."

He struggles again to ask,"Nurse are my testicles black?"

Finally she pulls back the covers, raises his gown, holds his penis in one hand and his testicles in her other hand and takes a closer look and says,"There is nothing wrong with them."

Fnally the mans pulls off his oxygen mask and replies
"That as very nice but, I asked ARE MY TEST RESULTS BACK?"
