Senior Prank

After their exams, the seniors decided to play a prank on us juniors & the whole school. This was what happened to our common room:

Upturned chairs

Normal chairs replaced with little stools - a la Vietnam

Bind up lockers

Vandalised windows :P

Balloons in the hallway! This was meant to be in the elevators

Bathroom window

Blocking the entrance :P

But apparently there was a lot more cooler shiz but the cleaners cleaned them :(
Anyway, time to think of MY senior prank as it's less than a year away!

What did you do/will do for your senior prank?
