Saw this on Woothemes Demo Server, which is a totally random place to find content. In case you don’t know, Woothemes is a pretty cool place to find cheap WordPress themes, which you can use as a basic layout for any website, not just a blog. (Check out one of their themes in action at Spain Soccer Jersey, one of my other sites.)
Anyway, the video is reminiscent of Justice’s D.A.N.C.E video, so if you are into that sort of thing definitely give it a play. If you’re really into t-shirt videos, also check out my post on the Guiness world record for most t-shirts worn at the same time.
