I stumbled upon the work Corey Smith on Trend Land and was instantly awed about his art and after reading his interview I deduced that he's also a witty chap. His art, often with hint of violence and cynicism, touches on cultural and political criticism and to me seems like an aggressive 21st century version of the works of Andy Warhol, although I think that's probably just because of his use of repetition.
You can find more of his work at his website. These are just a couple of my favorites.
