Apparently Microsoft in the UK commissioned Ricky Gervais and Steve Merchant to do internal training videos on working at Microsot, sort of as a spoof, but also fun type of thing, and it unintentionally got leaked onto the internet. The original story on digg said that Google and YouTube pulled the video at Microsoft's behest, but here's a link that looks like it's still functioning.
The double triple thinker in me would guess that perhaps this is part of Microsoft's campaign to change its image, by doing viral video marketing like this. Could be, could be. I mean, I actually think a little better of Microsoft if they have the good thinking to have Steve Merchant and Ricky Gervais produce just about anything for them.
