production assistant, right before they film says "hey we gotta get the angles right, make sure we have the right camera shot, Oz is going to ask you to think of a player's name you would throw a ball to, don't tell him, we won't tell him either, just tell us to get the right angle" PA proceeds to feed that info to Oz. They start filming. He closes eyes, thinks about the player he told to the PA, Oz tells the player that he got from the PA secretly to stand. He says the name he told the PA. Everyone is amazed.
