I have to admit it -- I don't watch football, not even the Super Bowl. I have however, considered recording the Super Bowl just so I could skip everything else and only watch the commercials. But, of course, with access to the Internet I don't need to.
Google Video is presenting all the 2006 Super Bowl commercials in one place for free. You can even watch all of them in sequence if you have 20 minutes to spare. They have even encluded some of the commercials that never aired on TV becuase the censors thought they were too racy for the game audience.
