A card is selected from a deck. A sticker is signed by the spectator and placed on the card. The card is then shuffled into the deck. The cards are sprung on to the table and an attempt is made to catch the selected card with the Lethal Teeth. When the attempt fails and the selected card is located, the selected card has a corner bitten off! When the teeth are inspected the corner of the card is shown to be inside the teeth!
Fun trick to do.
