An old man was in hospital. Lying in bed, he leaned over to the pretty young nurse attending to him and whispered in her ear
"Give us a kiss, luv!"

"No!", replied the nurse

"Oh go on!", said the man

"No!", replied the nurse again

"Please!", begged the old man, "Just a quick peck on the cheek?"

"For the last time, no!", said the nurse, "I shouldn't even be wanking you off!"
