A few years ago, my wife and I were at some store looking for bathroom accessories (tiles, toilet, etc..) and not too far from us another couple was doing the same with their child in tow....well, not quite in tow. Apparently, the parents didn't mention to this little girl that the plumbing wasn't hooked up....and she was proud as a peacock that she'd gone 'potty' and didn't have an 'accident'.....Oooops!
