Would I be correct in assuming that the simunition carries the same wallop as a paintball? I know a paintball can break a window. Don't ask me how I know that. So even if he does draw and fire the right weapon. The students are looking through a window that he's going to fire simunition at. If he's misjudged his range then the simunition breaks the window sending shattered glass flying into their faces. I'm just having a real hard time seeing where this "joke" has any punchline to it at all. Even if he does fire the right weapon, it's ha ha now you're going to have facial scars?
