Laughing so hard you pittle a bit

Okay so apparently this has been around since 2009 but I've never seen it.  I laughed so hard my co-workers seem to think I was having some sort of attack.  Seriously, either I am already drunk just THINKING about our Christmas lunch or this is some funny @$$ $hit! What kind of weirdo sense of humor do I have that YouTube decided that THIS would be a perfect "suggested" video?!?!? Good doG, I'll never be about to look at 10 the same way again...

Are you f**king kidding me!?!?!?

I can't embed the video because the user disabled that feature BUT the link is above.  If you've seen it before...sorry but I hadn't so I am sharing. 

It is synced perfectly.  I mean if I didn't know any better I would think he is in fact doing that...in his pants.

I can't even right now *snort*

I can't decide if he's laughing...crying...or uh a, should be a part of the video...HA!
