Sister blog Overheard in the tech blogosphere is pointing to a rather clever video from Bill Gates’ keynote at the Consumer Electronics Show earlier this week. It’s a mockumentary of Gates’ last day as Microsoft Chairman — a day that includes playing Guitar Hero, rapping with Jay-Z, soliciting top Democrats for a Vice President nomination and trying to convince Bono to let him replace The Edge. Other celeb cameos include George Clooney, Jon Stewart and Brian Williams.

Check out the video here – and try not to daydream about your retirement just yet.
