ON THE bottom of regular pack place the KD, and next to it a double-faced card, AH-KD, with the KD side showing. Borrow a hat, show the two bottom cards and drop them from the pack into a hat, but awkwardly and visibly let another card fall also. Remove the double-faced card as the KD and place it in a glass, covering it with a handkerchief and give the glass a half turn as you move it away. Order the two cards to change over and take the KD from the hat, uncover the glass and show the AH. When challenged about the third card, bring out an ordinary card, or you may use one with STUNG on it.
