At tonight's Microsoft Keynote, dear ol' Steve Ballmer made it a point to include plenty of lame jokes, gimmicks, and antics. Whether all of them were intentional, we'll never know, but here are our favorites.

Yes, those are a crazy cat lady's Twitter page, a skydiving Sea Hawk, some censored boobs, Steve's anatomy homework slides, and half-loaded old-school Internet porn. What some of those we're doing on the screen, I'll never understand, but I've gotta hand it to Ballmer. The man knows how to give us something to laugh about.
