One time in middle school, I was with a fren watching a school basketball game. For some reason, maybe relating to an event earlier that day, everyone in the crowd had elastic wristbands like pic related. People were bored (attendance may have been mandatory; I don't recall) so they were using the elasticity to shoot the bracelets into the crowd, as you might do with a rubber band. This picked up steam pretty quick and got to the point where a teacher had to turn around and tell people to stop. Naturally, my fren told me he'd give me a dollar if I did another one. I agreed, took the wristband, and fired it discreetly when the teacher's back was turned. It landed close to her, and she was pissed, but it couldn't be traced back to me. My fren gave me the dollar and I bought some chips or something. He totally didn't think I'd do it, but a dollar is a dollar.
