In high school, took a networking class, the teacher of said class was the district's IT specialist. Somehow our school accounts in that class has admin access to the entire network, which allowed me to do shit like install Counter-Strike across every machine on the network. There was always a gane going after that, and even some teachers were joining in. One of them asked me to get Diablo installed too but unfortunately, that game actually checked the CD-Key even for LAN so it couldn't be played the same way as CS and I wasn't going to use mine for it lol.
