Had the greatest low-flush toilet
at the first house my wife and I bought. The guy that built the homes was really into energy efficiency. The toilet was a Swedish concoction and instead of a flush lever, there was this ball on the top that you pulled up to send the gallon or so of water down in a torrent.
Maybe I'll see if I can find that toilet on an internet search. In the 3 or 4 years we lived in that house only one guy plugged it up and the turd was one for the record books. We still to this day have no idea how he managed to get that out of his body but it's a common drunken party story.
