We weren't meant to misbehave, because they set our group year picture for 2.30pm with the smug thought that this would keep us clean until then. Oh no. It did not. We went mental anyway, then we all got kicked out of school by 10.20am and told to come back for our photo, so we went to my place, recharged all our ammo and had a massive water fight in my garden, then went back to school to continue the mockery. We stole all the trays from the dining hall and hid them in lockers. We put polyfilla in all the keyholes. We put cling film over all the door frames so people walked out into them. That's probably the best three. The dinner lady was going mental for days and days after we left apparently. Oh, and we were all sloshed too.
