Joe Biden was giving shout-outs to local lawmakers during a rally in Columbia, Missouri, yesterday, when he got to Missouri senator Chuck Graham. "Senator Chuck Graham is here! Stand up, Chuck! Let 'em see ya!" he shouted spiritedly. And then: A look of absolute horror crosses his face. Graham is a paraplegic. "Oh, God love ya, what am I talking about?" Biden stammers, and then tries to save. "You can tell I'm new," he quips. "Everybody else stand up. Stand up for Chuck, everybody!" Nice.
