Hey, grumpy New Yorkers! Let's dance!!!

If you have ever been on a New York City subway car, you know it's a bit of an impersonal place where people rarely make eye contact, say hello, or show any signs of life at all, other than looking miserable.

Meir Kalmanson of AMK Productions decided to throw a DJ dance party on one of the trains and surprisingly, the bash looks like it was a success.

The video of course has gone viral and now you can watch citizens of the greatest city in the world loosen up and finally have a good time.
