and everyone his in mass hysteria running and screaming out of the building. But you know it's a fake. What would you do?
Either take advantage of everyone, by pretending to disable the bomb, or, wait until everyone realizes that it is a Saturday.
Depends on the teacher. One I like; see if they're are okay, one I don't know; leave 'em, and if it's Mrs. Garcia; lite her on fire.
I pretend to dismantle the 'bomb' and look like the hero. Then get all the ladies when I tell them my manly story of how I saved everybody. This is the only true answer.
You get the ladies until the bomb squad reports that there are no signs of a bomb anywhere and when you cannot provide evidence.
I'd find the fattest kid in the school, lure him up into the science lab with a donut, feed him tonnes of beans, carefully place explosive material 'round the room, n' place a buson burner between his legs. There will be an explosion tonight! >:3
Swap the fake for a real one and sit back and watch the school explode miles away from it in college. You'd do the same if you met the staff and saw the local area around it.
