Movie stars have a habit of taking themselves a little too seriously. But, every once in awhile, an actor comes along who isn't bashful about poking fun at his or her personality. For example, take "Joyful Noise," which opens nationwide this weekend. In one scene shown in the trailer, Dolly Parton's character pokes fun at the fact that she has had a lot of plastic surgery (something that the real Parton has had), as she eloquently states, "God didn't make plastic surgeons so they could starve."
In honor of Parton in "Joyful Noise," let's take a look at nine movie stars who have successfully made fun of themselves on film.PHOTOS
