When I was growing up, our next door neighbour was a nightmare. He lived on his own with a huge Great Dane dog called Jeeves. One day, he decided he was going to turn his back yard into a big water feature.
He began digging up the whole back yard - not with a spade but with mechanical diggers. Once he got down to about 12ft down, he began bringing in concrete mixers, and putting in reinforced steel everywhere. I tell ya, the Romans would have been proud of this mega-fountain construction! All day and night you could hear the concrete mixer going, power tools, dig-dig-dig... it was dreadful. It looked like he was laying foundations for a skyscraper.
Only trouble was, our back yard started sliding towards this massive crater, and poor Jeeves had no yard any more so he just roamed the neighbourhood (I was only a small child so I was terrified of him).
He still hadn't finished it seven years later when we moved out. I went back a few years later and noticed the whole yard had been filled in. And Jeeves was gone. I think I know where he ended up...
