The chosen card, signed by a member of the audience, is lost in the deck. Incredible as it may seem, it is the spectator himself who will find his own card in the face down deck! Even more astonishing, the signature as well as the face of the spectator's card will disappear in a very clear way; the card becomes entirely white! To rematerialize this card, simply make a magic pass over the deck and the signed card reappears face up in the middle of the deck. The magician then turns the other cards over and to his amazement, they are now all completely white!  

Like Dustin Hoffman in "Rain Man", you want to show your exceptional instant memorization skills. After thoroughly shuffling your deck of cards, you announce that you have memorized the position of the red and black cards; but in demonstrating this, you fail miserably! But surprise, you say that half of the cards are red-backed, and the other half are black-backed; and that in truth, the cards have been sorted by their backs!!!
