Yeah, nah, it's not an exaggeration. Even as a kid the first time I saw "illegal opeation" on a Windows machine I thought it meant something actually unlawful had occurred. In the early 90's there was a prank Extension for Mac OS called "Radiation" and a partner application called "Trigger". Trigger would allow you to pop up a system alert dialog box over the Appletalk network on whichever machine had the Radiation extension installed, allowing some nice pranking opportunities. The default message was "The radiation shield on your Macintosh has failed. Please step back five feet." … It worked, and some people would literally jump away from their desk when they saw this message! Ahh, the good old days hahaha :) (If you're still skeptical, I can probably dig up a copy of this software since I surely have it on an old disk somewhere, but of course I can't prove people moved away from the computer -- there's only my anecdote to go by here haha)
