On the opening night of Blog World Expo in Las Vegas, Zappos hosted a party at Prive (at Planet Hollywood). Half way through the evening Zappos CEO Tony Hsieh introduced Judson Laipply – the dude who is internet-famous for his YouTube “Evolution of Dance” performance that is almost at 100 million views.

Judson, who was in town already for business as a motivational speaker and comedian, then treated us all to this abbreviated version of the dance montage.
