Do You Know of Video Clips about WOM, Buzz, and/or Undercover/Stealth Marketing?

I am compiling a list of video clips about WOM, buzz, and/or undercover/stealth marketing to be used for teaching and illustration purposes. Here are two to get the list started:

1. 60 Minutes segment on "Undercover Marketing" (October 2003)

2. "Triumph of the Shill" segment in The Corporation (2003)

3. "The Merchants of Cool" "Under-the-Radar Marketing", Chapter 2 of Frontline video (2002)

NOTE: These three clips obviously focus on the ethically suspect practices of undercover and stealth marketing, but I'm interested in video clips of all different forms of word-of-mouth marketing.

Please add in ones you know of through a comment. Thanks!
