Most annoying, and the least amusing, of all the types of college students is the philosophy major—that pain in the ass whose idea of clever humor is to frustratingly ask, “Yes, but why?” to every response one offers in conversation. So how is it that Harvard philosophy majors Thomas Cathcart and Daniel Klein, authors of Aristotle and an Aardvark Go to Washington: Understanding Political Doublespeak Through Philosophy and Jokes, are so damn funny? Well, maybe it’s because they’re picking pretty easy targets: In the national embarrassment that passes for the United States government, every political quote is good for a punch line. More likely, it’s because—for a pair of philosophers—Cathcart and Klein don’t do a whole lot of heavy-duty philosophizing, opting instead to focus on the simple logical fallacies that many politicians have made a living out of spewing forth. Plato, it’s not. But Cathcart and Klein consistently drop comedic bombs with an accuracy that their targets have never achieved in Iraq. Cathcart and Klein discuss and sign copies of their work at 7 p.m. at Politics and Prose, 5015 Connecticut Ave. NW. Free. (202) 364-1919.
