The best-kept secret in Washington has nothing to do with nuclear codes or Dick Cheney's undisclosed location. It's this: Al Gore is actually pretty funny. Funny enough, in fact, that he managed to raise a daughter who wrote for "Futurama." (Also "Saturday Night Live," but let's just forgive her for that.)
Gore does pop up now and then doing cameos in various comedies -- like Thursday night's episode of "30 Rock." He's always at his best when he's making fun of himself, as he's done a couple times in "Futurama," and this was no different. Watch it below.
