Be Link or Young Link, and have a friend be the same. Now stand right next to each other, facing each other, and have your friend pull out a bomb. Now get him to jump once (a full jump, not a small hop) and drop the bomb on your shield while you are standing still. If the bomb hits the right place, the bomb will bounce off your shield, go up, come down and keep bouncing off your shield until it just explodes. It looks very funny and the turnip does not break the target; it actually goes through it.
