Remember that scene in The Dark Knight when the Joker crashes a ritzy soiree at Bruce Wayne's house and gets all creepy in that Joker way? Well that guy whose mouth he almost cuts off at the end of the scene, the one that looks a lot like Vermont Senator Patrick Leahy, is Vermont Senator Patrick Leahy! The Senator, who endeared himself to the world when he pissed Dick Cheney off so much that the veep told Leahy to go "fuck himself," is no stranger to the caped crusader: he's already lent his voice to Batman: The Animated Series and had a cameo in the worst Batman movie ever, Batman and Robin.
