A scene from my favorite Sopranos episode: "D-Girl"

Pussy: You lookin for a purpose in life? Doing what's right is your purpose.
AJ: That's not what Nitch says.
Pussy: Who?
Matt: Nietzsche. Let me tell you something: Nietzsche wound up talking to his horse. And I know what you're gonna tell me: Sartre, right? Well, Sartre was a fucking fraud. He copped it all from Husserl and Heidegger... You should start at the beginning. Take a look at Kierkegaard.
AJ: Whatever.
Matt: Hey, Kierkegaard said, "Every duty is essentially a duty to God."
AJ: "Nigga be a leader, not a follower."
Matt: What?
AJ: Master P said that.
Matt: Wait, you still listen to rap?
AJ: Why?
Matt: It's just all about marketing now.
