The world's most entertaining and useless self-help guide, from the brilliant mind behind the wildly popular webcomic xkcd and the million-selling What If? and Thing Explainer For any task you might want to do, there's a right way, a wrong way, and a way so monumentally bad that no one would ever try it. How To is a guide to the third kind of approach. It's full of highly impractical advice for everything from landing a plane to digging a hole.
