Reminds me of the time Dad and the neighbor agreed to split the price on a new fence. Dad had the fence built and went to get his money from the guy and the guy refused to pay him. They went back-and-forth for a week until one night we hear screaming and banging outside. The neighbor had a few cocktails decided to settle the matter.

With a sledgehammer.

He was able to knock down "his half" of the fence before the cops arrived.
