In this sequel to the best-selling Uncle John's Presents Book of the Dumb, guest author John Scalzi casts a wide net to bring readers more mind-boggling dumbosities perpetrated by dumb-doers. This time, to prove that dumb-nastics are not a modern phenomenon, Scalzi digs into the past to unearth some of history's most ill-advised blunders. The lesson: Dumb is as dumb does. And you'll be smarter for reading it.
