On a school Mac I figured out using some command I could create a new admin account. I used this account to gain access to the school WiFi password and admin account password. I found out what a vpn was and brought my own laptop to us instead of the crappy ASUS Eee PC netbooks. The Vice Principal was not happy. They called my parents for a meeting ( I had a lot of issues with many IEP meetings). My parents were okay with it.
We would also pass around pirated GTA 3, GTA Vice City, Free versions of Minecraft, and Halo CE and run them off of USBs.
