09 My New Philosophy (You're a Good Man, Charlie Brown 1999 Broadway Revival)

Sally is clearly cross about a D her teacher gave her on her homework assignment. In response, she says, "Oh, yeah? That's what you think!" Schroeder hears and asks why Sally is telling him that. It quickly becomes Sally's new "philosophy", and she bursts into song about her philosophies. Schroeder, after failing to explain to her how philosophies work, leaves in bafflement and frustration while Sally continues.
