I found this T-shirt over at slashfilm.com in the cool stuff section. It is so full on win that I had to post it. Ya'll can be hatin' for the short post, but this is for the people who might not have seen it had I not posted it.
I like the fact that the Jokers face is not platered on it. It's simple, to the point. It screams, "don't fuck with me or I'll make you into a unicorn."
