As I'm sure you've noticed, kids books --- traditionally shaped picture books --- are incorporating more traditional comics stylings lately. I checked this one out of the library and it was good for a laugh. Parts of the book are comics, parts are faux blogs, some Poe parody of varying goodness, all sorts of fun stuff. Here's an example of the comics (although they vary) snatched from Amazon because I'm too lazy to make a scan:
Adam Rex --- don't know a lot about him, but with this book and an image like that below (from his website) I know enough to know I want to know more. Best I can tell, he hasn't published any straight comics, but The True Meaning of Smekday sounds awfully good for the meantime.
