I once decided to talk with a "Hi this is Windows your computer wanted me to tell you it has a virus" guy once, and he's going through his script, trying to determine whether I have a Windows box or a Mac by describing whether I have a command key or a win key on my keyboard. My fancy-pants programmer keyboard happens to have neither, but in trying to explain this to him, he got so mad I literally heard him throwing things off his desk, last of which being the phone itself. I assume my family is still cursed, though I never took his physically improbable suggestions.
