"Dr Fox recounts the tale of one doctor who had scribbled TTFO - an expletive expression roughly translated as "Told To Go Away" - on a patient's notes.

He told BBC News Online: "This guy was asked by the judge what the acronym meant, and luckily for him he had the presence of mind to say: 'To take fluids orally'." "

This last bit sounds like an urban myth to me.
