A card is selected from the deck, folded in half widthwise, and the center is torn out so an actual hole is created in the middle of the card.
Next, you borrow a bill from your spectator, fold it in half lengthwise, and place it between the card’s folds.
The bill can be clearly seen through the hole at all times throughout the routine. With a (borrowed) pen or pencil, you now stab right through the center of the bill! The pen is unmistakably punched right THROUGH the center of the borrowed bill and is clearly shown on both sides!
