Recommended Daley Allowance

The Effect:

A stunningly visual version of Dr. Daley's Trick.  The four Aces are shown.  The spectator holds the red Aces.  You show that you have the black Aces.  You make the cards in your hand switch places with the spectator's cards.  But Daley used Aces and you do the trick with Queens.  You show that the cards are now the four Queens!
