The Extraordinary Adventures of Baron Munchausen

This not-quite-a-role-playing-game requires players to sit around telling fantastic (but completely true!) stories. Players may attempt to trip up another player's story by wagering a token ("But the Prussian Army had dissolved by that time, m'lord, so you could not have possibly fought it single-handedly"), whereas the storyteller must counter with another token (and an excuse) or swallow their pride and incorporate it into their story (with another excuse). There are also a few, minor details, mostly used to get boring storytellers to stop. The game is won after each player has told one story. Each player, in turn, gives all their tokens to another player they believe has told the best story--so collecting the most tokens doesn't make you the winner, it makes you be able to choose the winner. Of course, the best story-telling wins the game.
