The narrative of Edgar Allen's Poe only novel, Arthur Gordon Pym, is about an Antarctic voyage that didn't end so well. In one of the scenes of the novel, four shipwrecked survivors end up on a raft and come to the conclusion of eating the cabin boy, Richard Parker, to survive. In 1884, Migononette, a real life ship, sank and left four survivors. These survivors, also decided to cannibalize the cabin boy to survive. Their cabin boy's name was also Richard Parker.
Dr. Seuss's children's book "Green Eggs and Ham" was written as the result of a bet Seuss made with the publisher of Random House. Bennet Cerf bet the author (whose real name was Theodore Geisel) $50 he couldn't write a book with 50 words or less. Geisel took him up on the challenge, producing Green Eggs and Ham, which contained exactly 50 unique words. Cerf never paid up.
