Aww, this brought up a fond nineties memory.
I got busted installing Shit Talker (1.2 by Jaundice!) on all of the computers in the economics classroom and scheduling them to disparage the economics teacher throughout the day. In my defense, he was an idiot.
I was banned from using any school computers for the remaining two years of my high school career, so I built a mini-PC (using parts my dad “borrowed” from work) in a portable file box and carried it from class to class, using the school PC network connections, monitors, and peripherals.
