Billy Bob Teeth
The inventor of Billy Bob Teeth, who’s also known as Caveman, found his idea after looking deep into a fire. He brainstormed cheap and inexpensive items to sell for $20 or less, and after what seemed like ages, came up with one of those weird inventions that eventually made him and his family rich. We’ve probably even worn these teeth for a Halloween costume at least once in our lives. Once he came up with the idea, he sold them everywhere he possibly could, like every house, shop, and everywhere in between (STL Mag).
