I'm sorry. I apologise in advance for this, but I just caught a couple of minutes of an old Countdown with Jimmy Carr.
One of the guests, whose name I have no clue of, just advised that she loves finding new words, and that her favourite is Anatidaephobia. Which basically means that somehow, somewhere, a duck is watching you.
I just looked it up to be sure it wasn't a joke. It's not. It is a genuine word. It is defined as a pervasive, irrational fear that one is being watched by a duck!!
I think that is the absolute maddest word I have ever heard. Had to share it - hilarious!!
