Google uses video ads to promote... Google Video. In one of the ads, they show a popular video from Google Video and ask you: "Have something better? Upload and share your video now."
Something better than "Hips don't lie spoof", "Webcam girls go wild", or "Steve Irwin gets stung by a stingray and dies"? What about "Webcam girls killed while singing Hips don't lie"?
