A signed card is lost in the deck.
Having been unable to retrieve it, the magician forfeits all that he has in his pockets to the spectator. A business card, a wristband, a sharpie – and a sealed pack of gum.
As the spectator makes to walk away with his prize, the magician stops him, asking for a stick of gum. With a look of INCREDULITY, the spectator tears off the cellophane, opening the pack – and there, sitting amongst the sticks, is the SIGNED card.
