Memorable Moment?

My teacher once took me out in my entire class and said ‘let’s see how much you got what I taught you’.It was a pretty hard calculas question but fortunately I solved it a day before that day.So after all the obstacles I handled it and told him a funny thing I once heard in a movie “I might not have a brain but I had an idea” and he was like wtf did you just tell me?.I was like you think you are the only best one here.
