You show a white board with black spots. There is one spot on one side, four spots on the other side, three spots on the other side, and six spots on the other side. What? Does this board have four sides? How can that be? You can repeat the sequence.
You tell the audience that you will let them in on the secret. You go through the motions of explaining how the trick is done. But wait, now there really are 6 spots on one side and 3 spots on the other! For the finale, one side of the board has EIGHT SPOTS!
A terrific routine with a Killer Finish.
