Obviously not the best with photoshop, and it was quick... but you see the point. Personally. I think it looks great without the tats. Even with the body tats, put him in the suit and he'll look perfect. The grills work because Batman's knocked that many of his teeth out, over the years. May also have accidentally eradicated one of his nipples there, oops.
The Joker is NOT a common thug life gang lifer nor would he ever choose to look like one.
At least not permanently. I could see him up to something of course.
Major fail. Hope it's not real.
