Senior prank stories?

<p>In one neighboring school, the computers are networked so that all the data is accessible from any computer in the system. The harddrives with the data are all in one room. A few years ago, they brought either a strong magnet or a bunch of normal magnets (I don’t remember which) into the room where the network harddrives are stored, wiping everything (including grades).</p>

<p>In a different neighboring school, the seniors painted windows in one major hallway black, causing the temperature to become dangerously hot.</p>

<p>People were suspended in both cases (which is not really unreasonable).</p>
