Just remembered some more things:

We once had to sit in a class staying silent and doing nothing for a 45 minute lesson because someone had scratched a counter in the food tech room with a knife.

Another interrogation was someone on our table broke a cocktail stick in a Science lesson there was three suspects: Me, my mate and the person who did it, but the person who did it wouldn't admit to it and everyone knew he did it but in the end it got to the point were it became unfunny and annoying so my mate said he did it.
