Yes, it does.
Try this one: while talking to your spectator about whatever, go through the deck right in front of him and pick a card yourself. Stand there holding it and talk to your spectator for thirty seconds. Then hand him the card you selected, and talk for another thirty seconds. While you're talking, spread the cards into a nice big fan. Then pause, holding the fan horizontally and face down, and ask if he's sure that's the card he wants.
"Uh... yeah."
You will never, ever, ever wonder whether a force will work again - no matter how stupid it looks on paper.
