oya..we used to have these catapults we make in class out of
hole punchers, pens and rubber bands. so anyway we kept firing
20cents erasers at each other and sometimes hit the teacher. i
rmember once i constructed this dam complicated structure of a
catapult but when i fired at someone the eraser couldnt even lift
off 
also i used to go into thick crowds of children during class and
raise my hand whenever the teacher asks a question, after which i
would say,"it wasnt me, but that guy/girl/both sitting in front of
me"
quite irritating, no wonder i didnt haf friends then
