Train tricks...

Occasionally, while sitting on the subway in New York City, the conductor comes on the PA and yells at us kids telling us to "let the doors close in the back of the train" (or the front or something) and I always think, "You know, most people don't really pay attention to where they are on the train so it almost doesn't matter whether the conductor says back or front, except that if they get it right the wiener holding the door might think that there's a camera or something." Of course today, the conductor said it was the seventh car. He could still be bluffing.
