Over the years, you see some pretty crazy things while holding open houses.  Several years ago, a young family came in and asked to use the powder room for the little boy.  Apparently there was no toilet paper so the boy used some of the hand towels for this purpose.  When he flushed, of course there was a clog and the toilet overflowed.  The boy was so embarrassed that he did not tell anyone.  A few minutes later, we found that the water had come out of the bathroom and ruined much of the hardwood flooring in the living room.  Needless to say, the open house had to be shut down.
