Threw snowballs at cars from a service road, so they couldn't stop and come after you. Convinced little neighbor kid (with help from his older brother) that rabbit droppings were raisins. Switched plug wires around on dad's straight 6 (he shut it off after 5 seconds of running like crap, figured it out, fixed it, then beat my ass). Stuck little green apples on the end of a fishing pole, flipped them over the house out onto the main road during rush hour. Best: My buddy lived near the ball diamonds, there were train tracks running past, with lots of thick vegetation to hide in. Grabbed his wrist rocket slingshot and an M80 (the old 1970's kind, that were really loud), went down to the tracks and hid in the bushes. There was a girl's softball game going on. M80 in leather pouch thing on the wrist rocket, pull back all the way, lit it, waited a couple of seconds, aimed toward the softball game, and let 'er rip. Up, up, up, up, down, down, down, UH-OH, UH-OH, please go off, please go off, KA-BOOM! Exploded about 6 feet over the pitcher's head, scared the crap outta everybody.
