Seinfeld Gates Commercial

What the hell was that TV commercial? I heard something was going to be coming out to "counter"(?) popular whimsical Apple commercials. I just saw the this latest Seinfeld /Gates commercial. Seinfeld is trying to get Gates interested in shoes (I have not idea why ). Seinfeld recommends wearing the shoes in the shower (what the hey?). Seinfeld and Gates then go walking in the street. There is some talking of something consumer oriented but nothing more. I am sure there were will more commercials like this but all I can say is "WHY?"
