Gonick's books -- he's even done the Cartoon Guide to Statistics, which made even that lucid, fascinating, and hilarious -- are, in my opinion, to be recommended wholeheartedly to every one. I don't think I've ever learned so much, so quickly, so effortlessly, so enjoyably. Everybody, go buy a copy of everything he's ever published, right now, and read it all. (It won't take you long.) You'll thank me.
