You try to plant the bomb but you don't have a bomb nor the materials to make a makeshift bomb.
You run after students stabbing them with a pencil but you stab the wild weeb, making him go unconscious again!
You then run to the cafeteria to obtain a cheese grater, then think about grating half of your face. You refrain from doing so as it will be very painful and everyone will think you're a freak.
