I’m pretty sure that I first saw this video at a conference in Portland, and it was pretty impressive at getting the point across. At the end of the video, it only briefly gives credit to the creator, Michael Wesch - Assistant Professor of Cultural Anthropology at Kansas State University.

I just managed to stumble across it again, through a mention at Christian Mezeis blog, and it turns out that the video was available on You Tube where it has had over 4 million views already.
