Blagues : Black Testicle ?

A man suspected of SARS is lying in bed with a mask over his mouth. A young auxiliary nurse appears to sponge his face and hands.
"Nurse," he mumbles from behind the mask, "Are my testicles black?"
Embarrassed the young nurse replies: "I don't know Mr. *****, I'm only here to wash yourface and hands."
He struggles again to ask: "Are my testicles black?"
Again the nurse replies: "I can't tell. I'm only here to wash your face and hands."
The Head Nurse was passing and saw the man getting a little distraught so she marched over to inquire what was wrong.
"Nurse," he mumbled, "Are my testicles black?"
Being a nurse of long-standing, the Head Nurse was undaunted. She whipped back the bedclothes, pulled down his pajama trousers, moved his penis out of the way, had a right good look, pulled up the pajamas, replaced the bedclothes and announced: "Nothing wrong with your testicles."
At this the man pulled off his mask and asked again: "I SAID...Are my TESTS RESULTS BACK!!!???"
