I heard a few strains of Ozzy, but couldn't get anywhere near close enough to see.
Although I'm a fan of Stewart/Colbert, I was pretty skeptical of this whole thing. But people came and made it their own, which in general was a mass repudiation of the Teabagger movement.
I'd feared that it would overwhelmingly be douchey twentysomething hipsters trying to be ironic, which is what I imagine the Comedy Central core audience to be. But it was a very diverse crowd in terms of age and walks of life.
The only person I saw who didn't get the memo was a sole 911 Truther... dude, you and your ilk are as wacked as the Teabaggers. Cut from pretty much the same cloth.
Beyond that, we've had the media telling us for so many months that the teabaggers are a rising force, it was nice to be reminded that there are real Americans, from all over the place, who do not subscribe to their toxic creed.
