As the nation readies itself for another three weeks of presidential campaign debates, Jon Stewart and and Bill O'Reilly are about to go head-to-head in a verbal sparring contest of their own. The 90-minute "Rumble in the Air Conditioned Auditorium" takes place this Saturday at The George Washington University in Washington, D.C.
Fox News anchor O'Reilly appeared on "The Daily Show" Thursday night to promote his new book, "Killing Kennedy," and to engage Stewart in some pre-Rumble teasing.
