I'm not a fan of fight videos
but this one is crazy: Two guys get smashed over the head with beer bottles at the Cowboys game in San Diego last weekend. (But the guy who keeps showing his bloody arm needs to realize he's not in critical condition.)
Edit: Oops. BagofNothing.com had this first, but it's funny that we both made comments about the Arm Guy.
Edit: From youtube comments: "I'm just glad that somebody finally filmed a fight video in HD, while holding the phone horizontally, and not shouting 'WORLDSTAR' every 4 seconds."
