so what happened today was so funny and disracting

SO today we had a sub & he always says "No bullying & Y u bullying me (he got it from the boys at school)" then while we were working a boy showed up and the sub went very mad (I guess he was rude in one of the science periods) the boy kept saying Y U BULLY ME while the sub was going to get security the boy came in the class and stand on a table jumping up and down but guess what security never came :T
