Microsoft regularly makes funny videos starring its employees, and probably wishes that some of them would never again see the light of day. But the Internet is a meticulous archive keeper, and this week an old video surfaced of now-departed executive Brian Valentine masquerading as John Belushi's Bluto Blutarski in a video spoof of "National Lampoon's Animal House." This is one of the best videos we've seen of a Microsoft executive willingly engaging in self-humiliation -- and clearly enjoying it. That hamburger-eating scene? Amazing.

How about a video of Bill Gates inserted into the video game "Doom"? Former Microsoft game employee Alex St. John showed the 11-year-old video last month during his keynote speech at the Penny Arcade Expo. It's still available online. The video features Bill Gates wearing a trenchcoat and brandishing a shotgun in the game "Doom," and was shown at a promotional event on Microsoft's campus.

"Windows 95 is THE game platform," Gates said. Later, he shoots a bad guy and growls menacingly, "Don't interrupt me."
