Dude I have the best school sign vandalism story
Each class had a hallway to decorate: Seniors had the front hallway, and then in another section of the building, there were three hallways, the topmost belonging to the freshmen. Usually it's kinda fun to see how good the seniors' hallway is in comparison to all the rest, and how sucky the freshmen's hallway was. This time around, though, they put in a whole ton of effort and got organized (this being my senior year, I didn't participate in any of this.) Each class had a theme for our "winter carnival," so the general scheme that year was elements. Freshmen were air. They were kinda grasping at straws to figure out good slogans, and eventually came up with "WE WILL BLOW YOU AWAY" in big huge letters. All was well for a few blocks that day. However, somebody had the idea to take off the "AWAY," just leaving a massive "WE WILL BLOW YOU." This not being enough, later in the day it was stripped down to the much more concise "WE BLOW." They took some time to recover from that embarrassment, but it was hilarious for everyone else.
