If there's anyone in this world who could afford to hire Jerry Seinfeld to help promote its products, it's Microsoft. For its new $300 million campaign, which aired during NFL's first regular season game Thursday night, the 90 second spot featured Seinfeld, Bill Gates, shoe shopping and a churro. Though we have to admit the commercial was a bit odd (to say the least), it definitely was a bit of a surprise to see the computer guru shake his money-maker at the end.
