After spending 30 years building one of the world's biggest technology companies, how will Bill Gates spend his last day at Microsoft before retiring in July? 'I'm not sure what that last day is going to be like, so I asked some friends to help me prepare,' says Gates, who unveiled a riotous spoof video at the recent Consumer Electronics Show in Las Vegas. Bill's Last Day, on Microsoft.com and YouTube (keywords: 'Bill's last day'), shows him job-hunting in earnest. Gates trains in the gym with actor Matthew McConaughey, raps Big Pimpin' with hip-hop king Jay-Z and beseeches Steven Spielberg for a movie gig.
