25 years ago, when I was in high school, I hacked the computer network, got access to the administrative account and then changed it - locking out, completely, the actual administrators. The next day I was pulled out of class and brought to the principles office. They said "give us the password and you go back to class and that is the end or we expel you (and then they'd have to format and build the network back up)." I gave them the password and went back to class, end of story. Imagine if that was today, I'd be royally fucked.
