While I do fnd him funny, he probably says that based on the fact that larry the Cable guy has never written one joke in his life. He is a performer, not a comedian. His entire bit is made up of obscure Foxwrothy bits from when he was starting out, a few old Hickman tales, and more than a couple Tracy one liners, and he stole and compiled from numerous others.
He has a nice overdone stereotypical routine, but he is alrgely a one trick pony.
