where i found it: alongside blood on the ice
Behind the main building of the New York Public Library (pictured above) lies Bryant Park ice skating rink, where over the weekend some kids shot each other over a Marmot Mammoth. I had no idea what a Marmot Mammoth was. Turns out it's a coat. Worth shooting someone over. This article predates this (apparently only the most recent) shooting, but it covers all of the bases, including where you can go to buy one. If you're too much of a wimp to get one for free using your glock.
