This post needs a disclaimer: Yes, I know that Jimmy Fallon is, as a rule, scarily unfunny. But the segments of his late-night show in which he "slow jams the news" with The Roots, his house band, are actually quite funny. And they're surprisingly informative to boot.

Below, the newest one, this on low Democratic voter turnout and what it means for 2010. (No, seriously.) If you don't trust me on the humor level, that's fine, but know this -- there is a joke in this video that involves a comparison between conservative favorite Doug Hoffman's loss in an upstate New York Congressional race earlier this month and premature ejaculation. And it actually makes sense as an explanation for Hoffman's defeat. - Alex Koppelman, Salon
