Doogie Horner may be the world's only stand-up comedian / book designer, and he pretty durn good at both. (He's currently designing the book I wrote earlier this year, and I'm pretty sure it's going to be great.) He's responsible for the now-famous cover of Pride and Prejudice and Zombies, but he was just on America's Got Talent doing stand-up (and got pretty far, I'm told, for a comic). When he's not doing either of those things, he's designing flowcharts. Hilarious flowcharts. In fact, he wrote a whole book of them. It's called Everything Explained Through Flowcharts. One of my favorites is A Graphic Guide to Facebook Portraits, a snippet of which is below. You can see the whole thing here.
