Jon Stewart, Bill O'Reilly

Forget Obama vs. Romney! Jon Stewart vs. Bill O'Reilly is sure to go down as the debate of the century.

O'Reilly challenged The Daily Show host to a debate, dubbed "The Rumble in the Air-Conditioned Auditorium," during Monday night's The O'Reilly Factor.

The event, set for Saturday, Oct. 6 at 8/7c at George Washington University, will take place before a live audience and will stream online for $4.95. Half the profits from the debate will benefit charities.

The throwdown, which will feature both men at podiums like in the actual presidential debates, seems almost too absurd to be real. In fact, after Stewart finished taping Monday night's Daily Show, during which he accepted O'Reilly's call to arms, he returned to the audience to clarify that the debate wasn't a joke.
