Ahaha man reading this brings back so many memories.
MY year did these 2 nights before our "muck-up day":
- Glued a heap of little toy army men to the ground outside the science labs - it's a balcony and there's only one way on the path
- Climbed a 2m high gate and took all the doors off the stalls in the boy's toilets
- Gladwrapped the paths leading to the 7/8 building and library
- Chucked glitter everywhere
- One of the dumbass guys took a shit in the middle of the breezeway
- Smashed lights & broke locks to the shed with boltcutters which went waaaaaay too far
- Silly string fights
- Oil & flour was thrown everywhere in the canteen which was really stupid, a teacher actually fell over the after we did it because she didn't see it
- Honey & glue on the bannisters
AND, the ultimate prank, for which I won't take credit for since I wasn't a part of it:
