A man in hospital beckons an hospital employee to his bedside and asked her
"are my testicles black?".
She said that she was sorry, but this was not her ward and besides, she was only
a cleaner and walked off sharpish.
A short while later he beckoned a nurse to his bedside and asked her the same
question "are my testicles black?".
She lifts the bed clothes and his night gown and checks his tackle and replies
"no, they look fine to me".
He leans over to the bedside table, takes his false teeth out of the glass and
pops them in and says "no no, are my test results back?"
