Via CrunchGear the above video is allegedly being used by Microsoft as an internal promotion tool for encouraging sales of Vista. We’ve defended Microsoft’s takeover offer for Yahoo a number of times previously, but watching this you sort of understand why Yahoo employees are scared.

Update: Long Zheng notes that this video is the real deal (not a spoof) as Kevin Turner, Microsoft’s Chief Operating Officer makes an appearance. Other reports are suggesting that it’s a Microsoft developed internal spoof. What ever it is, it’s bizarre.
