A recent episode of GAC-TV's 'Day Jobs' showed Clay Walker as a dedicated cattle rancher before -- and even after -- his country music career. That wasn't the only less glamorous job Walker held, however. He also did cleanup at a tire factory, worked nights at a motel and sold shoes.

By age 19, Walker had become a successful touring act across Texas, and just a few years later, he was in talks to sign his first record label contract. Five of his first six singles reached No. 1, making the singer a star by age 25.
