What I find to be quite peculiar, is that there is a certain, small group of FReepers here, who are so quick to try to pooh-pooh all the other FReepers' observations about this weird clip, and are trying so stridently to get all those other FReepers to stop focusing on these strange aspects of the video... The answer to your Query may lie here.
Lord Oddsocks says: We can do better than waste time on a short clip, which has been explained on plenty of other threads.
