My Worst Nightmare

I came home from giving my girlfriend a lift to work this morning and heard a strange noise from the living room. I ran in to discover water cascading from an on wall "Mr. Slim" indoor air conditioning unit onto my stereo. I naturally freaked, pulled my whole rack to the other side of the room and then surveyed the damage. Not too bad actually. I'm in the midst of an amp trade, and despite bemoaning the lack of an amp the night before, the empty bottom shelf is where most of the water fell. The only casualty if any may be my Chang Lightspeed 3200, which was fairly well doused. But all in all, I got lucky. What's the worst thing that ever happened to your system?
