I don’t know if this is really a prank but way back when, many many years ago…
This school sent home papers saying that 3rd grade was going on a field trip and classes were canceled for the day. As luck would have it, it started raining so the field trip was canceled. The administration told everyone to get back to class, one boy lets call Bob, said hey wait we can’t go back to class, classes are canceled and organized a strike against the school. Only a few people listened and didn’t go to class. He got suspended and a few years later got expelled.
