My high school computer lab in 1998-99 was full of Windows 98 machines running a program called "Fortress" which was meant to lock it down and prevent tampering.

I made a custom boot disk (floppy) that would boot Windows bypassing Fortress. It was pretty easy.

During computer programming class I'd install Worms on the machine and we'd all play.

The instructor was a cool guy and said it was fine as long as we were getting our work done.

On one of the tests he included a question: "Who is the master of the ninja rope?"
