Yup, I've done the "forget the RO filling a 5 gallon bucket."

I also went on Vacation for a week, and came back to find my 60 gallon tank half empty... powerheads barely running (I didn't have a sump at this point). I think the HOB skimmer overflowed somehow and pulled 30 gallons of water out. Thankfully everything was ok.

Then there was the time I was up for some unknown reason at midnight (thankfully), and I heard a sound of water... I thought "what's my wife doing having a shower at this time of night when she has to work in the morning?" The flexible hose popped off the return pump (in sump, and therefore no hose clamp) and it was shooting water at 700GPH all over the inside of my stand. I had to tear the tank down to dry out the carpet in our apartment.

The worst I think was when I was working with some live rock in a tote. I had a heater and a powerhead running in it. The next thing I know I'm grabbing the powerbar out of the water before I realize that I could have been seriously electrocuted if it were not for the AFCI breaker in the panel popping. That was scary.
