When I was a teenager, the next-door neighbors left their dog outdoors while they were at work. The dog would bark ALL day. I politely complained but got the answer that their dog was a good dog and would not bark all-day. Of course, the dog would stop barking as soon as its owner would come home.

This went on for months and months. All the neighbors were annoyed. Finally I recorded the barking and told the rest of the neighbors what I was going to do.

That evening I put my two huge stereo speakers in the window facing the neighbor's house. As soon as they got home I started to play it back. It was at the same volume as when recorded.

The neighbors came out of their house and told me to turn it down. I told them that the recording was their dog and that is what everyone had to listen to every day.

The husband looked mortified but the wife wanted to pick a fight.

After about an hour, I turned it off but told them that I intended to play every day until they did something about their dog.

About two weeks later, the dog disappeared, but the neighbors never said anything about it.

They moved several months later.
