A man is lying in bed in a Catholic hospital with an oxygen 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 your face and hands." 
He struggles again to ask, "Nurse, Are my testicles black?" 
Again the nurse replies, "I can't tell. I'm only here to wash your face 
and hands." 
The ward sister was passing and saw the man getting a little distraught 
so marched over to inquire what was wrong. 
"Sister," he mumbled, "are my testicles black?" 
Being a nurse of long-standing, the sister 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 them!" 
At this the man pulled off his oxygen mask and asked again, "Are my test 
results back???
