Ok, normally I don't link to blogs for the comments, but Bob Johnson at DailyKos posted what is on track to become the largest ever thread at dKos-- over 1300 comments!
The best part: it's a fake diary about how much he loves the Bush administration!
Bob got a couple of the bigger dogs on kos in on the act, and before they knew it, they had gotten hundreds of people posting on it. And I gotta tell ya, the comments are hysterical!
If you have time, I would strongly suggest wading in to check it out. It's a piece of blogging history.
