Larry the Cable Guy
He became famous for creating the "Larry" character. It is a personality that he now uses for his entire stage act. The Larry character has a stereotypical redneck appearance and a thick Southern accent. He tells stories about his fictional "family".  He is well known for his catchphrase "Git-R-Done!" A large part of Whitney's act is his accent. He says in interviews and in his autobiographical book GIT-R-DONE that he uses the accent both on and off stage. He does this because he may forget it if he kept his normal accent. He uses catchphrase humor, including "Git-R-Done," "Lord, I apologize, and me with the starvin' Pygmies down there in New Guinea. Amen." and "I don't care who ya are, that's funny right there" after certain jokes.
