A beautiful young woman is about to undergo a minor operation.
She's lying on a trolley in a hospital corridor, awaiting medical attention, when a man in a white coat approaches her, lifts the sheet covering her, and performs a physical examination of her body. He then walks away poker-faced, consults with another man in a white coat, who approaches and performs the same examination.
When a third man approaches, the girl asks, concerned, "is everything okay? When is the operation going to begin?"
"Your guess is as good as mine, lady," the man says, shrugging. "We're just painting the corridor."
