From Larry West. Five blank cards and one 8 ball card are shown on both sides. The spectator chooses a face down card from the six. The choice is the only odd card, the 8 ball. The spectator chooses again from the six cards. The magician triumphantly shows the face of the chosen card without looking and states, "Again, you have chosen the odd card. However, the card is blank." When the "error" is called to the magician's attention, he shows that the blank card is, in fact, the odd card by revealing that the five remaining cards have magically changed to eight ball cards.
