Interesting stuff. If you go read the whole transcript of the CNN Crossfire with Franken, it seems like Franken was trying to make fun of O'Reilly's explosive behavior by getting angry and whatnot. I'll bet he was trying to immitate the voice and mannerisms as well, although it's pretty hard to tell from a written transcript.

Unsurprisingly, NewsMax didn't get the joke or chose not to get it, instead reporting on the one place where they could take Franken out of context. Amusingly, this is precisely the sort of thing that Franken documents in his book on the right-wing media. There's something ironic about them trying to do the same thing to him so transparently.
