Happy Birthday, Steve BallmerS

You've seen Steve dance before. Today, if you are using Windows, sending emails from your Hotmail account, or even editing Excel spreadsheets, I insist you do a little monkeyboy dance in your seat. For Ballmer—the ever-entertaining CEO.

Turning 54 today—exactly 11 months to the day of the other Steve—Ballmer also shares his birthday with the ninth anniversary of the OS X launch. But we'll be popping the cork tonight for you, Steve Ballmer—our favorite monkey dancer who ensures there's never a dull moment in the tech industry.
