I use them for practicing card control. I assume the Joker is the "selected card", that way I can see how well I'm controlling it. For example, I can place a Joker on top of the deck, then false overhand shuffle through a few times. If, when I'm finished, the card on top is still the Joker, then I know I did it right.
