Stewart, Colbert: 'Rally To Restore Sanity' vs. 'March To Keep Fear Alive': On 30 Oct, John Stewart's "Rally To Restore Sanity" will meet Stephen Colbert's "March To Keep Fear Alive".

Jon Stewart and Stephen Colbert will march together on Washington. Or against each other in Washington. Either way, expect plenty of Comedy Central fans to show up on October 30 when Stewart's "Rally To Restore Sanity" will meet Colbert's "March To Keep Fear Alive" in the nation's capital.

The duo have been hinting at a major announcement for several episodes in a mock response to Glenn Beck's own "Restoring Honor" rally that was held this year on the anniversary of a famous Martin Luther King speech at the same monument. There's no indication that the announced get-together is a joke, though. Both comedians are telling their audiences to book hotel rooms now (though for different reasons, as you'll see).

"It'll be like being in a chat room," Stewart explained. "But real."

Stewart punctuated his announcement on the earlier program with a homemade-looking banner reading, "Take It Down A Notch For America."

Colbert followed up with an announcement on his own show, and insisted that he would "notch it up a scotch."

Each man ventured into the other's studios for moments you'll just have to see for yourself ...
