You hand five jumbo playing cards to a spectator and keep five for yourself.  You both place them behind your back and remove one card.  Holding them face down, you trade.  Then behind your backs you flip them face up and insert back into your packs of cards anywhere you like.  You bring your cards in front of you and fan them.  Both of your face up cards are the face of Jesus!  Turn the rest of the cards over and they're ALL BLANK!  You use this to illustrate, that if you will only believe, His help is available to you.  And... IT'S A REAL FOOLER!
