take them down
The year above mine set of every single fire alarm at exactly the same time, fire alarm going off for 3 hours straight.... dunno how it works but they stopped one and the next one went off...they couldn't sort out all of them at once so they kept setting the rest off lol

or something like that...
Great day that was

, apart from that... our year didn't do anything special

dunno why

we just wanted to get out lol
