[flashback to Barney and Marshall on the street:]
Marshall: This is me yelling at you, Barney!
Barney: Okay, you got some volume, now give me some content. Make it hurt.
Marshall: You don't look as good in suits as you think you do!
Barney: No, something that's true. Come on. The man made you cry. Make me cry.
Marshall: Your mom's a slut!
Barney: Yes.
Marshall: Your mom's a slut, and I'm sorry, Barney, but you and your brother clearly have different fathers, And you know why? It's probably because your mom is a slutty slut!
Barney: Keep going.
Marshall: I don't care what you say. Bob Barker is not your father!
Barney: Okay, now, well, that's just not cool.
Marshall: Oh, my God, Barney, I'm so sorry...
Barney: No, I'm kidding. Keep going.
