Stung – a sucker card trick

The magician shows three jumbo cards and wraps them in a mat. Removing two of them from the mat, the magician says that the third card has vanished. The audience is not impressed because they see the third card peering out from behind the mat. After the usual business, the audience demand to see the card which turns out to read STUNG. Still not satisfied, the audience ask to see the back of the card. The magician finally turns it round to reveal STUNG AGAIN.
