5. Jon Stewart incites a near-actual crossfire
Tucker Carlson and Paul Begala couldn't debate their way out of a damning indictment from guest Jon Stewart, who was promoting his book "America (The Book): A Citizen's Guide to Democracy Inaction" in 2004. He claimed their show Crossfire was "hurting America," and after Carlson tried to rebound by asking Stewart about his own style of interviews, Stewart responded, "It's interesting to hear you talk about my responsibility. I didn't realize -- and maybe this explains quite a bit -- that news organizations look to Comedy Central for their cues on integrity." Harsh, funny words. Three months later, CNN canceled "Crossfire" (it has since been revived with new panelists including Newt Gingrich) and CNN CEO Jonathan Klein said he sympathized with Stewart's criticisms.
