Replying to Senior prank

ours was surprisingly pretty funny, we had an academic rally where they give out awards for the people who are the most academic in a certain subject, well we waited when the whole gym was quite and i stood up in the senior bleachers and yelled YAHTZEE and everyone in our class threw bouncy balls in the gym, we ordered about 10,000 bouncy balls, they covered everywhere, then everybody just started throwing them at each other, i myself threw some at my teachers i did not like so much, but that whole thing for some reason made a 10 minute rally into a 2 hour rally of everyone picking up the bouncy balls. pretty fun
