Video on the net is always iffy. When I’m in interactive mode, stopping to sit and watch a tiny video is hardly worth it. Lately I’ve found a few which are worth the effort:

Sacramento TV News Report on Geocaching
If you still don’t get Geocaching (or know someone else who doesn’t), this video is a good intro.

Snow Tow
You know what’s going to to happen, it’s just a matter of when.

Hey Ya!, Charlie Brown
This is better than both the real Hey Ya! video and the classic Peanuts special. Unfortunately it’s been taken down for copyright reasons, but it’s widely available on Kazaa or other file-sharing networks. For Macs, Acquisition rocks.
