Fun trick

Usually people shut up when you do something like this:

Luser: "Well what's the worst that can happen if I do that?"
Me: "Theoretically? Theoretically the worst thing that can happen is that it opens a black hole at the core of the Earth and sucks all existance into the event horizon, dooming us all to oblivion."
Luser: ".....?"

I have too much fun with this job! It's the only way to stay sane :-D
