Yes, Some people may have left already and some may be leaving soon, What pranks have you played/will you play?
Last year put soap and water in the corridor and watch people fall over, last year a teacher fell over and broke her hip LOL!
This year we're supposed to be putting fish behind radiators or releasing balloons filled with stuff like shaving foam into the hall with helium so when they get popped it falls on everyone lol.
