For his role in "Hesher," Joseph underwent a pretty astonishing transformation. Wearing a scruffy beard and long, stringy hair, he looked thin, dirty and uncharacteristically unkempt. As a social misfit, he put in an effective performance, but we can also look at his portrayal another way. It's a cautionary example of the value of good grooming. There's no doubt that fashion works from the skin out. Keep your hair trimmed, your teeth white and your nails short. Oh, and get clean and stay that way. If your date can smell you coming, it won't matter much what you're wearing.
