How do you stop your students from doing dumb things? That is a question professor Pawnsworth had to ask himself a lot of times, because as the head professor of the summoning course in the Emperial Univerity, whenever one of his students did anything wrong he would get yelled at for it. So what did he do to stop this from happening? Why drill every single even so minor thing into those young heads of course. Which cut down the accident rate like you wouldn´t believe, but of course he knew that this wasn´t enough to stop children from summoning something they really shouldn´t. So he fell back on the oldest trick in the book telling them stories about the things they should never summon and why.
