My dad knows one card trick. He's very proud of it. He'll shuffle a complete deck of cards, offer you them face down and ask you to pick a card, any card. He will then proceed to tell you which card you've just picked. 'The Joker', he'll say, smilingly. And, sure enough, it is the Joker. However, considering this pack comprises fifty-two Jokers, it's hardly magic. But it keeps my dad amused.
