The performer says that the greatest advantage in being a magician is that, by using the powers of magic, he can correct mistakes. He proposes to demonstrate using two playing cards. One is a red-backed heart card, the other a blue-backed spade card. He points out that each has the cut out of a card pip in its center. The heart card shows the cut out of a spade — the spade card, the cut out of a heart.
 
"Obviously, it's all wrong" he says. "It should be the other way round." He goes on to state that the average person couldn’t possibly correct such a mistake. "After all, you can’t simply erase the heart cut out and change it to a spade — nor can you rub out the spade cut out and make it a heart."
 
However, the performer makes the claim that magicians would find it a simple matter to switch the cut outs. He holds one card in each hand with his fingers covering the cut outs. After lightly touching the cards against each other, he withdraws his fingers from the cut outs to reveal that the cut out of the heart is now in the heart card and the cut out of the spade, in the spade card!!
 
Following this first climax, he explains that he must change the cut outs back to the way they were to have the cards ready for a future demonstration. "However, it’s harder for a magician to do things wrong" he says. "It calls for stronger magic. I’ll have to snap my fingers the way stage magicians do when they vanish elephants." Following a snap of his fingers he shows that the cut outs have again switched: the heart design is back in the spade card — the spade design, back in the heart card!
