1. I was on the train back home last night and there were a bunch of assholes at the 57th stop keeping the doors open for one of their friends for an obscenely long time (#5 in the "How to Be Rude on the Subway" photo below).
It went on for awhile, and of course the train can't leave when there's an idiot holding the doors open. They do this all the time, and everyone else on the train hates it and groans and mutters to themselves (the cardinal rule for commuters in NYC is to remain anonymous), and the train conductor usually yells at them through the speaker, never to any avail. But out of nowhere I screamed "GET OFF THE TRAIN!" and the one holding the door looked at me, stopped grinning, let the doors go, and got off the train.
2. Walking to work today, I came to the corner of 2nd and 70th and saw one of those huge industrial hampers on the corner amidst a pile of trash, and there were legs sticking out of the top of it. There was stuff piled in the hamper, so I couldn't see if the legs were attached to anyone. They had some Nikes on and white socks, and jeans. Definitely human legs. There was no smell, so I figured he wasn't dead. I walked on and forgot about it until just now.
