One of my all time favourites, this one. A homeowner decided to connect a wall light to an old Lead Sheathed cable. The instructions said that it required an earth. Easiest option? 1) fit an old rusty jubilee clip around the cable sheath. 2) stick a bit of earth wire stripped out of some flex beneath the jubilee clip. 3) Realise that the jubilee clip is a bit slack so fit a broken clothes peg to take up the slack. 4) tighten clip 5) stand back and admire ingenuity and think of the money saved by not getting an Electrician in. The UK is now 'slowly' trying to regulate Electricians and electrical work; but that's another story.
