Details are scarce (i.e. in another language and I'm too lazy to translate) on this video, but here's what we do know:

• A man is riding a motorcycle near a marina
• It doesn't go well

The one thing I do know about this video is that it's fantastic.  I watched it about a dozen times and it still wasn't enough.  I wish I knew the back story, so feel free to pass it along if you can read whatever language that is in the YouTube video description.
