The fictional "Godfather of Black Surf Music" who is now completely forgotten and washed up. Preston works as an auto mechanic, and is best known for randomly breaking into song while performing his mechanical duties. He often distracts himself and irritates others when reminiscing on things that involve his trademark song, which consists only of Preston singing "Don't you know no good!" over and over. He is seen mostly in the first three seasons. He makes one appearance in the fifth and final season.
