From the underside of the box: "Would you believe... Mice prefer women to men! Handkerchiefs originated in China! The Niagara falls are turned off at night! Sitatunga antelopes can sleep underwater! Hummingbirds can't walk! Match a beginning on one card with an ending on another to make an Unbelievable statement. Only you know whether the statement is true - the others have to guess. You can back your statement with a bet, but someone might call your bluff! The player with the most chips after four hands wins the game. Lots of fun, educational and challenging, and above all, always Unbelievable! (TM)"
