Oooo! I HAVE LOADS!!!
OK. The best one that i remember happened in my first year of secondary school, it was probably the moment that has made me and Kate laugh to this very day. It was a hot autumn afternoon in History, sir was blabbing on about some s*** that nobody really cared about, he caught some boy chewing gum and called him to the front to spit it out, he was in front of the whole class and i don't know how it happened but he just dropped. But it's the way he fell that made us laugh SO MUCH. He fell like a tree that was just cut down.. Me, Kate and some boy called Haytham still laugh to this VERY DAY it was soooooo funny.
May last year, exams

.. Everyone finished about 10/20 minutes early. Some boy fell asleep and started snoring LOL. As the teachers woke him up his desk broke and he landed on his face! LMFAO!
The Great Big Stokey Water Fight!!! 3/4 of the students from my school in our local park in the summer having a huge water fight. The park rangers called the school and 4 teachers came to try calm us down. If i remember correctly it was; Mrs Pascell, a wrinkly old prune that retired but still works in our school!?

. Mr Byeno, ICT teacher who is NORMALLY NICE. Mr Pickerell.. MR PICKLE and Mrs Wright. Anywaysss, word spread of the teachers coming and everyone stopped getting each other, we all planned to get the teachers. Cut a long story short the teachers failed and went back to school soaking wet without catching one student
