Believe it or not, I actually set out to try to explain this video. It turns out that there's no point. What I say wouldn't make sense anyway.

Just know that there's 24 minutes of insanity here. I died laughing...several times. 

It should be said that this is going to do more for an otaku than anyone else. Still, there's something here for everyone. 

I love Nico Nico Douga. If you're one of the typical web video viewers that stops watching after 10 seconds, your loss.
