Inspired by my sudden discovery of The Extraordinary Adventures of Baron Manchausen: A Game of Telling Tales and Playing Roles, the rules of which involve wagers, wine and one-ups-manship, no really, drinking, gambling and boasting appear to be core parts of gameplay and the entire thing is written by The Baron himself (or at least in very good mimicry of The Good Baron, but anyone whom disputes the authorship may findthemselves at the end of his rapier in short order).
Anyone else got any truly bizarre discoveries of things you'd NEVER expect to have a roleplaying game?
