competition: What you should never say to a teacher

i was in religion class, as i went to an all girls catholic school, and this teacher was a real cow and pretty obese to, which i think added to the comment.and to one of my friends she said "you never going to be anything" to which my friend replied " maybe, at least ill never be a 40 year old virgin"

hehe she ran out of the room screaming "your all bitches" XD its not that funny as it is cruel now i think about it.
