A beautiful young woman was about to undergo a minor operation. She was lying on a hospital trolley bed with nothing on, except a sheet over her.
The nurse pushed her trolley down the corridor towards the operating theater, where she left the woman on the trolley outside, while she went in to check whether everything was ready.
A young man wearing a white coat approached her, lifted the sheet up and started examining her naked body.
He put the sheet back and then walked away and talked to another man in a white coat.
A second man came over, lifted the sheet and performed the same examinations.
When a third man did the same thing, yet even more carefully, she began to grow impatient and blurted out:
"All these examinations are fine and appreciated, but when are you going to start the operation?"
The man in the white coat shrugged: "I have no idea. We're just painting the corridor."
