I wanted to hate this, and I tried not to laugh, but it's pretty well done. Some gratuitous swearing around 4:30. Also watched an interesting profile on "YAC" - John Yacobellis, King of NYC Bike Messengers. It's dated, maybe 10 years old, but that makes it more entertaining. Here's another messenger profile about Dog-Paw (SF), circa 1992. This one is hilarious.
