Hotel by Ludovic Mignon

You give the spectator an envelope containing a prediction. You then hand the spectator a stack of business cards you've collected from various hotels you've stayed at over the years. While your back is turned, the spectator goes through the cards one at a time. He chooses one and puts it in its pocket. Once you turn back around to face the spectator, you immediately know which hotel he has chosen!

Now you decide to take the experiment to the next level. The spectator goes through the stack of business cards again. Again he stops on the card of his choice. You then ask him to open the envelope, in which he finds a room key from the hotel he has just selected!
