Mervyn's department stores ran a number of advertisements featuring the voice of Kongar-ol Ondar and Richard Feynman.  They were kind enough to provide us with a copy; one of the ad spots is available here as a RealVideo file.  This spot is titled "Yo-Yo" (Martin/Williams Ad Agency for Mervyn's California).

* Streaming video looks terrible on slow-speed connections -- so this video clip has been optimized for high-speed connections.  This makes for much higher image quality and smoother action.  If you have a slow connection, this means that the entire video will download to your computer before it plays.  Be patient -- it's worth it!  The file is 566K in size and can be saved to your computer so you can watch it over and over again.
