The "Monologue Song." Whoulda thunk someone as sweet and innocent as Taylor Swift could be so sarcastic when she wanted to be?
The opening line from "Better Than Revenge" (and, to a lesser extent, the whole song):
"Now, go stand in the corner and think about what you did."
The Fridge Brilliance of the line in "Better Than Revenge", "She thinks I'm psycho cause I like to rhyme her name with things.", when you realize it's a Take That at Joe's new girlfriend following Taylor's breakup with Joe, Camilla Belle.
