I know how you felt. Many years ago when I was a junior working in a casual game company, I were to add a bunch of credits to a poker player (fake money). I forget the where in the SQL clause and added credits to every player in our database. Lucky me it was an add and not a set and I could revert it. Another time I was going to shutdown my pc (a debian box) using "shutdown -h now" and totally forgot that I was in a ssh session to our main game server. I had to call the tech support overseas and tell him to physically turn on the server...
