Okay, if you go to the Fox News site, you can watch the interview. Unfortunately, I couldn't find a way to directly link to the video, so you'll have to find it manually. As of this writing, there's a link on their front page.

And just to let you know, O'Reilly loses. Not necessarily because Moore beat him on the issues, or out-debated him. No, in fact, they both danced around the issues quite a bit. The real reason O'Reilly lost? As per Official Internet Flamewar Rules, the first person to bring Hitler into the discussion loses. It's that simple. Ol' Bill went all in with a big Hitler reference, and the rest is history. Moore 1; O'Reilly 0. Schwing! :)

I don't know if this has aired, but c/o the Drudge Report, here's a transcript of Bill O'Reilly's interview with Michael Moore. Very interesting read. :)
