He’s trying to trick you into buying a pair of shoes. This is an example of viral marketing. Millions of Web surfers fell for an online video demonstrating the art of “liquid mountaineering,” aka running on water, in summer 2010.

It was also totally fake – an advertisement for the brand of shoes worn in the video.
