A joker is a little fool who is different from everyone else. He's not a club, diamond, heart, or spade. He's not an eight or a nine, a king or a jack. He is an outsider. He is placed in the same pack as the other cards, but he doesn't belong there. Therefore, he can be removed without anybody missing him.
Jostein GaarderIf just one of [those people] experiences life as a crazy adventure--and I mean that he, or she, experiences this every single day... Then he or she is a joker in a pack of cards.
Jostein GaarderThere is always Joker to see through the delusion. Generation succeeds generation, but there is a fool walking the earth who is never ravaged by time.
