Anon: I think that someone has been cheating off my tests, and I worked really hard to get good grades. What should I do?
War Hawk Advisor: Get two scantrons and use one as a fake and the other as your own. Leave the fake within seeing distance and watch the suspected cheater. If they start copying you, yell "CHEATER" as loud as you can, and rip up their scantron. Replace it with your fake one, and say "You would've gotten a zero either way." You may then proceed to snap your fingers and walk out of the school with all the sass in the world.
