A beautiful young girl is about to undergo a minor operation. She's laid on a trolley bed by a lady in a white dress and brought to the corridor. Before they enter the room she leaves her behind the theatre door to go in and check whether everything is ready.
A young man wearing a white coat approaches, takes the sheet away and starts examining her naked body. He walks away and talks to another man in a white coat. The second man comes over and does the same examinations.
When the third man starts examining her body so closely, she grows impatient and says: "All these examinations are fine and appreciated, but when are you going to start th operation?"
The man in the white coat shrugged his shoulders: "I have no idea. We're just painting the corridor."
