I’m in 8th grade, not highschool yet, but a bunch of my friends are handing out posters for a fake Backyardigans role-play club.  It’s spread across the whole school and we have at least one in each locker room that get replaced every time they’re taken down.  We press them against bus windows as cars pass by, stick them to classroom whiteboards, and tape them to various inside and outside school walls.  7th and 6th graders have started to catch on.  One kid printed 50 during 4th period supervised study and wasn’t caught (yet).
