Why on earth would anyone object to Where's Waldo (Wally)?, number 88 on the American Library Association's list of 100 most-challenged books (via). It's not exactly controversial, is it? It's a picture book, for crying out loud. And one with rather tame images at that. (Unless there's a Playboy version I've not seen.)

Update: Ah, I understand now. There really is a "Playboy" version. I think I even have the edition in storage at home...
