Well, well, well! Who's an ignoramus?!
If you've never seen the Doctor Who episode, Tooth and Claw, then you are silly, because Doctor Who rocks. But within that episode, a bit of a moral is... entwined? Anyway, to beat the werewolf, the Doctor and friends go scrounging in some books, where eventually, they do find ANSWERS!
Books are the best weapon because you can find practically anything in them, whether it be printed information, little scribbles around the edges of the words, or the need to bash people over the head with those delightfully hefty hard backs!
