I  wrote an article for Smithsonian Magazine (paid for but never
published) on "Mark Twain, The Father of Fake News," that I'd be happy
to share. His most famous hoaxes were written for the Territorial
Enterprise - Indians attacking Hay wagons, "The Petrified Man," and his
most outrageous, "Massacre at Dutch Nick's." After he left Virginia
City, he seemed to clean up his act.
