Maybe that image popped into my head because they're so bite-sized. I'm not sure. All I know is I am in love with (and have been for a few years now) the Pocket Penguins (btw, click on that link and then click on one of the spines. Enough to make you love Penguin, eh?). Since I always wear skirts and therefore rarely have pockets, I have recently christened these delightful book snacks as my emergency handbag book (you know, the one you pull out when The Husband is late, or you're stuck somewhere waiting). They are ideal. I'm currently into #47, and previously devoured #1 (didya know Forster testified at that?) and 45.
These also looks utterly delish.
