A movie about bike messengers doesn't sound that exciting, but this trailer is bad ass!  It's filmed using a helmet camera, and features some insane dudes on bikes, dodging in and out of traffic, inches away from death.

I can't imagine what it's like sitting on a bicycle seat when you have a set of marbles this large.  There were so many times in this video that I was sure was going to end in death.  Don't get me wrong, I'm sure these people are paid for their quickness, but whatever they are getting paid it isn't worth this.
