I've always been a bit of a prankster, too, but for some reason I'm blanking on a few of my best ones lol. That elevator/stairs one was hilarious. I'll never forget this one year where our principal made an announcement that we weren't getting enough class time in, so we would need to do away with recess for the remaining school year. Some of the biggest, baddest kids in our middle school practically broke out in tears. Thansk for sending this one in, Jeffrey!
