Pay attention to the description of the video! It reads '8 clicks from http://tstkeith.blogspot.com/2007/05/ ...'. Pretty obvious it is some referral statistics from YouTube. This suggests that YouTube has been putting its referral statistics in public allowing (extremely powerful) search engines like Google to access this information. I tried some other keywords but it doesn't seem to trigger the same "description". Could you find other keywords that produces the same (strange) video description? Or do you have other opinions about this phenomena?
