I've personally seen someone ask a question, "My cat keeps jumping on my keyboard. Is there anything I can do to make sure she doesn't accidentally type a valid Unix command while I'm AFK?" And the answer was, "When you leave the keyboard, type "cat" and press Enter. That will put Unix in cat mode, where it will be protected from cats typing random characters." :-) (That's not verbatim, it's from vague memory of something I saw a couple years ago).
