I had an "illegal operation" message once - when I tried to the computer
OFF!
I also had an illegal operation message once during an IT lesson in school. I was bored, so I clicked on the message and started moving it round the screen. The computer glitched and made it look like I had a million illegal operation messages on the screen!
...And guess who had a cover teacher who saw the screen and didn't understand what had happened? I <almost> got a detention because of it!
Stupid idiot teacher.
