I love it, the Wall Street Journal, reporting on a video on YouTube, in a column called “Time Waster!” Lasse Gjertsen’s YouTube video has no spoken language, zero sudden injuries and nothing in the way of narrative or pop-culture reference. No copyrighted material was harmed in the making of this film. Yet, in just a month, “Amateur” has been viewed more than 1.5 million times, according to YouTube’s tally, and the video earned the highest user ratings over that span — making it a certified viral-video hit.
