Belgian farmer accidentally moves French border
A neighbor once moved the pegs marking our block a few meters so that he could move (and claim) the neutral strip. The most irritating thing, is that he more or less got away with it because he was old and persistent. In fact, he gradually built infrastructure on it, despite hundreds of complaints to the local council and authorities. In the end the council couldn't come up with a good way to settle the dispute, so they offered to auction the neutral strip and its contents between us to the highest bidder.
