xkcd volume 0, by Randall Munroe
This is a collection of various strips from the
xkcd webcomic, along with some commentary and extra weirdness. For example, the page numbers are all in ternary, and there are extra drawings. The drawings are also presented in higher resolution than on the web, but that's not a particularly big deal.
There are occasional changes as well. For example, the comic on factoring the time is set at 2:07 pm in the book, while it was at 2:53 pm online (to my mind, much funnier). That's presumably some easter egg that I haven't yet deciphered.
Highly recommended, if your sense of humor resembles mine. (Check out the website first.)
