Urlesque unveiled the 100 Most Iconic Internet Videos -- the most popular and memorable viral videos in the history of the web. Since there's a lot to sift through, we'll occasionally feature an individual video from the countdown.

Howard Dean's Scream will go down in history as the first time the immense gaffe-amplifying powers of the internet joined forces with the 24 hour news cycle to totally kneecap a politician.

Millions watched the frightening clip over and over again, and decided Dr. Dean would make an awesome Chairman of the DNC. El Presidente, not so much.
