No free cars at this Oprah giveaway, but audience members will still get free transportation—to Jon Stewart's "Rally to Restore Sanity" on October 30 in Washington D.C.

The magnanimous talk show host made a special guest appearance by satellite on Stewart's Daily Show. "I think that we need a little more sanity in the world," she said. "I wanted to show my support for you, John, and also for your audience," she continued, telling him that her staff had sneaked into the studio earlier and put tickets under the seats. "You’re going to the rally! You're going to the rally! You’re going to the rally!” she shouted, in a parody of her own automobile largesse from earlier in the year.

Stephen Colbert, who had emerged from beneath a green-screen cloak to surprise Stewart earlier in the show, rebuked Stewart. "Just for the record," he said, "Your rally is supposed to be about sanity, and that was insane!" Stewart responded with a qualification. “That was insane for normal people,” he said. “Oprah could have built these people an ark, flooded the entire northeastern corridor and floated them down to the rally…She has her own network of angels.”

Later, Colbert mocked Oprah's appearance by giving out tickets to his audience to the march— on Chinatown buses. –AMY LEE
