Go to the Mario target test. Now, move to the left and jump onto the platforms that are going downwards. Notice that there's a small crevice where you're supposed to shoot a fireball to get a target. Well, with some good timing and a combination of jumps, up+B's, and dodges (L), you can get into that small area and hit the target yourself. There's not much you can do, but the roofing to the small path is messed up; your head pops through it.
