The now nearly common face-off between Jon Stewart and Bill O'Reilly begs the reader for certain expectations. One: Jon Stewart ought to dress more casually than Bill O'Reilly. Two: Jon Stewart ought to use fewer notes than Bill O'Reilly. Three: One of the two men ought to express underhanded affection for the other. Looks like tonight's debate over the rapper Common's visit to the White House--the first two parts of which will air on The O'Reilly Factor tonight and the final two tomorrow--passes muster. Can you guess the rap lyric Stewart uses to tell O'Reilly he's got "mad love" for him?
