Remember that movie "Broadcast News" starring Holly Hunter, William Hurt and Al Brooks? I caught a bit of it on the tube the other day and was reminded of the part where Brooks - trying to warn Hunter off - tells her that Hurt is the Devil. Hunter rolls her eyes at the apparent hyperbole and Brooks says no, come on, "what do you think the Devil will look like when he appears? horns and tail? no! he'll look just like that."
His point, of course, is that evil creeps up in disguise - because its evil. Anyway, I only mention this because it popped into my head while i read this story on the Beeb's website here.
