A story told to me by my mother, who once worked as a clerical officer at a District Hospital in Yorkshire. A man walked into Casualty Reception and announced, "I've got gravel !". The nurse on the desk had never heard of this ailment, so she fetched the Registrar, who hadn't heard of it either. He rushed to his office, and after frantically leafing through various medical dictionaries, summoned the Consultant.
The Consultant went to the patient and said, "Now then my man ! What seems to be the problem ?"
He replied, "I told you, I've got this lorry load of gravel outside. Where do you want it put ?"
