Last night on MTV's The Hills, we finally understood how someone like Spencer Pratt can wear someone like Heidi Montag down—she's young and (by some standards) beautiful, and yet totally, completely insecure and not very bright. Spencer is an ass, and an idiot, but he's managed to manipulate the bejeezus out of Heidi in the way that some guys seem to have been born to know how to do. Last night he came up with the most evilly brilliant line, one that will undoubtedly be used immediately by controlling manipulators nationwide. Whether you are the manipulator or the manipulatee, watch and learn.
