Ooh idea! Ok whatever don't listen to a noob but still.
1) Put a virus onto the computer (just make it noticable don't get one that just blows it up)
2) Name the exploding disk with something related anti-viral and see if you can slip it somewhere the admin(s) could use it.
3) Admin(s) slip it in the drive to try to fix the virus.
4) Boom AND they just got humiliated/in trouble.
