Mr Jillette and a friend of his got the idea to make playing card size copies of the Bill of Rights printed on metal. It sets off the metal detectors and you get to hear the security person say, "I'm going to have to take away your Bill of Rights." Well, it's not going to actually work like that very often, but the idea is there. They're light and go right into a breast pocket. Purchase 1 or 100 and hand em out to your friends.
