You bring out a blue-backed deck of cards, fan it and invite a spectator to merely think of any card. You now give the deck to the spectator - you never touch it again. The spectator goes through the deck and removes the card he is thinking of; let's say the Queen of Hearts. After a comedy prediction, astonishingly you reveal that the selected card is the ONLY red-backed card of the deck!
 
- Easy to do
