If you see some graffiti around town declaring November 11th there will be "World Screaming," don't alert Homeland Security just yet. The Brooklyn Paper points out that the message is really part of a marketing campaign for graf legend Dumar Brown's book, The World Screaming Nov (the "11" in the tags were meant to be quotation marks--see the one in Paris). His last book was called Nov York.

Brown told the paper, “It was just an advertisement. I didn’t have permission, but then again nobody ever asked me if it was OK that they put billboards up in my sight. I’m not a vandal.”
