It's a lousy screen capture, but the fuzzy blob riding the roller skates is Bill Gates and the fuzzy blob on the bike is Napoleon Dynamite.
If you're a fan of Napoleon Dynamite (like I am) it's a pretty funny video and it's all over the blogosphere. Napoleon has a sweet 10-speed, and Pedro has a Sledgehammer so how can any cyclist not be a fan?
Synopsis: Bill Gates (yes, that Bill Gates) has a roommate: Napoleon Dynamite. They work to upgrade the computer systems at the company owned by Uncle Rico and Kip. Hilarity ensues in Napoleon's understated style. Watch Bill get slapped by Napoleon. Watch Bill dance. Watch Napoleon make fun of Microsoft.
This video is a vidcam capture of the video from a developer's conference. The video is okay, but the audio quality is poor.
