Marty stops in his tracks and one of Griff Tannen’s gang members, Rafe “Data” Unger, pulls a piece of paper out of his breastplate and presses a button to trigger a chicken clucking sound effect.
Obviously, nobody in our 2015 is going to take something that looks like paintball armor and add sound effect circuits. If they do, they’re certainly not going to use some kind of paper tape to determine what sound effects to play.
