Seal Slaps Kayaker With An Octopus...What?

My first thought was "what did I just watch?! Did that seal just go 'thug life'?"  Then I watched it over, and over, and over.  At first it really looks like the seal is telling the kayaker to get out of his neighborhood. Apparently, the seal and octopus were just fighting (seal was probably hungry) and the kayaker just ended up at the most wrong place at the most wrong time.  The video is pretty awesome though!
