One of my favourite quotes from the late Terry Pratchett:
> When the first explorers from the warm lands around the Circle Sea travelled into the chilly hinterland they filled in the blank spaces on their maps by grabbing the nearest native, pointing at some distant landmark, speaking very clearly in a loud voice, and writing down whatever the bemused man told them. Thus were immortalised in generations of atlases such geographical oddities as Just A Mountain, I Don't Know, What? and, of course, Your Finger You Fool.
For me this kind of simple, straightforward, educational content is part of the reason I’m proud to pay my TV licence.
