This is one of my favorite things I've seen for a while. There's some back-story - Steve Ballmer is the crazy CEO of Microsoft who has gone out of his way to say things about Apple. Much reviled in the Apple community, he's also kind of an idiot. This "ad" was created from real footage of him at a Microsoft Developers presentation when he pranced around the stage screaming. It's a little unnerving to watch the real video, believe it or not (though you can still hear the vocal track in the background of this thing). But this is classic. More links to come, I'm sure.
