Ops story: I worked at a data centre which had an IP KVM attached to all of their machines. When you were logged in as 'admin', there was a mode you could toggle that would send all of your keystrokes to every server, but still only displayed the one you were logged into, so there was no (clear?) visual indication that this was going to happen. Coworker hit Ctrl-Alt-Del to reboot a stuck server, and rebooted every non-Windows server in the data centre (and we only had one Windows server). Every customer got some level of compensation, the noisy ones got a lot of it, and no one ever logged in as admin again other than to relabel servers in the server list.
