Been there, done that
I was loading a SPARCstation and had several xterm windows open to various other machines (as root , of course, young punk that I was).
Anyway, when the install was over I clicked on a window with the root prompt and typed:
reboot
It took me a few moments to realize that this window was logged into our main production server. (Hey, I *said* I was young and stupid, didn't I?)
Despite my size and (lack of) shape, I made record time going downstairs to give my fellow sysadmins the heads-up and try to minimze the damage.

"While I'm still confused and uncertain, it's on a much higher plane, d'you
see, and at least I know I'm bewildered about the really fundamental and
important facts of the universe."
Treatle nodded. "I hadn't looked at it like that," he said, "But you're
absolutely right. He's really pushed back the boundaries of ignorance."
