No matter how rude or nasty you might think they are, everyone farts, and that means everyone in history farted, as well. From the same man who brought you such flatulence files as Who Cut the Cheese? and Blame It on the Dog, Did Somebody Step on a Duck?: A Natural History of the Fart ($10) completes fart historian Jim Dawson's trilogy of gas past, from the world's first fart joke to a fart-obsessed Twitter user. Pretty much perfect for some potty time reading.
