Although they probably would leave exquisite corpses, I'm not talking about imminent death. Unless it's in the story.
Exquisite Corpse is apparently a game in which writers write a chapter each, picking up where the last left off. Other than that, no rules. Sound awesome yet? Wait, it gets better. Jon Scieszka wrote the first chapter in this game, with other chapters to be written by fellow children's lit writers. Chapter 2 is up now, written by Katherine Paterson. The game runs for a year, with a new episode by a new author every 2 weeks.
