I’m not exactly sure. I don’t remember them explaining that. And I never asked. But maybe I will.

My wife said when she was younger that they used to live near a golf course. And they constantly had a window that would be broke from a stray golf ball. But she also said that everyday there was hundreds of golf balls in the back yard so she would go gather them up and sell them back to the golf course to make a little bit of extra money.
