It makes me think of this Simpsons exchange:
Marge: Well, most women will tell you that you're a fool to think you can change a man. But those women are quitters! When I first met your father, he was loud, oafish and rude. But I worked hard and now, he's a whole different person.
Marge: (forcefully) He's a whole different person, Lisa.
