I actually got expelled from my school (in Scotland) for installing the 'MacinTalk' network chat software on our Business Studies AppleTalk network with about ten Mac Classics. The time I only got suspended was for using Prestel via the Computer department's (only) modem, after shoulder-surfing the password for the school account when a teacher demonstrated 'the future of computers' to us. The look of uncomprehending fear on the teacher's face as they ran into the computer lab after being told I was using the modem was priceless. I eventually had to go to an entirely different school to study for my Higher Computing, because none of the teachers at my school were competent enough to teach it.
