I stumbled onto Guys backflip into jeans on Youtube this morning. It is one of the top videos in the 'featured videos' on the homepage and had racked up 1.7m views in the past 5 days. I wondered whether they used camera tricks but I honestly didn't realise it was a Levi's ad.
Gawker did though and investigates the similarities between this and last year's Ray Ban viral. More here.
