Bill O'Reilly and Jon Stewart faced off in a spirited debate on Saturday night.
Though the "Rumble In The Air-Conditioned Auditorium" was far from the first time the two men have duked it out, the debate lasted much longer than any of their previous on-air skirmishes, and was held at a university in Washington, DC, not on television.
It was also not free to watch: you had to pay $4.95 to have the debate livestreamed on your computer.
