i had to run an errand yesterday afternoon, so I took the 6 to 33rd Street. My train arrives, I get off normally, and the crowd makes its way to the exit. All is well. Then, before I reach the turnstyles, this eastern european guy in front of me does this really weird dance twirl and small fist pump, right out of nowhere. I mean, the guy was a little overweight and lacked a good bit of coordination, it was clear that this is not something he did with any frequency. And he took up a lot of space in doing this, it was really obvious to everybody around. Some indian guy who was walking next to him gave a great "da fuck?" face.
that's it, as weird as that story sounds, it is completely true.
