Joe Berkowitz, writing for Fast Company, details how John Hodgman knows everything - and how you can too:
John Hodgman is unique among know-it-alls. Most earn this title based on attitude and a tendency to correct others during casual conversation. Instead, Hodgman took the much more direct approach of writing an entire trilogy of books containing the totality of world knowledge. Although some of the information in those books is not actually true–indeed, some of it is based on imagined hobo best practices of the 1920s and ’30s–the author still knows the information. Then again, as he explains, some of what we all know to be true is just generally agreed-upon stuff that somebody else made up.
