If it has sorry, did a search for euXQbZDwV0w only and it didn't turn up anything =P.
Well it may have been uploaded multiple times by now (considering it has gone viral), so searching for a single link won't help you.
That's true, my logic sat on, if it was a viral video, most likely the one posted on the most popular video site with the most views would have a higher chance of being already posted.
