We just can't seem to get enough of YouTube. Here's a list of the top 100 music videos, all of which are available on YouTube. I know it's not as entertaining as seeing Darth Vader work in a supermarket, but it could still be interesting, particularly viewing the videos of some of those 80's bands. Duran Duran, Flock of Seagulls...hmm...it's funny already.
Also check out this Google Video (I know it's not YouTube, but let's be video-provider-agnostic here, shall we?) for what life would be like if it was like World of Warcraft. Ouch.
