If shock value was worth money, Australian graffiti artist Lush would be rolling in  dough. With graphic scenes of genitalia, ripped heads, and breasts, Lush has managed to offend more than half of the Australian population. For over 12 years, he’s been plastering the street with his obscene art and he’s more than proud of it. “It’s the ultimate self-gratification, f*ck jerking off, it’s just a lot better to hear random people talk about you and say the most outrageous shit,” he told Acclaim magazine.
