Waiting for an operation

@rondetto Said

A beautiful young model 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 room she leaves her behind the theater door to go in and check whether everything is ready.
A young man in a white coat approaches, takes the sheet away and starts examining her naked body, then walks away and talks to another man in a white coat. The second man then comes over and does the same examinations. He then beckons to a third man who comes over and starts examining her body so closely that she begins to grow impatient.
She says, "All these examinations are fine and appreciated, but when are you going to start the operation?" One of the men wearing a white coat shrugs his shoulders and says, "No good asking us, we're just here to paint the corridor"
