Barney Stinson: That's why there's a little thing in corporate America I like to call the chain of screaming
Marshall Eriksen: The chain of screaming?
Barney Stinson: Yes. The chain of screaming starts at the top. Arthur's boss's boss screams at Arthur's boss. Arthur's boss screams at Arthur. Arthur screams at you. You go home and scream at Lily. Lily screams at one of the kids in her kindergarten class. Then that kid screams at her dad: Arthur's boss's boss. And the whole thing starts all over again; thus completing the circle of screaming
Ted Mosby: I thought you said it was a chain of screaming?
Barney Stinson: It's a circle, Ted. I called it a circle.
Marshall Eriksen: I don't scream at Lily
Lily Aldrin: And I don't scream at my kids. None of whom have parents that work at Marshall's firm.
Robin Scherbatsky: So it's not a circle
Barney Stinson: [Angry] Fine! You want it to be a chain of screaming? A chain of screaming. I come up with the circle idea halfway through because I thought it was a more elegant metaphor, but fine, RUIN it. You guys always undermine me when I'm trying to make a point and I'm sick of it. Argh! I'm surrounded by idiots. IDIOTS.
[Normal]
Barney Stinson: See, doesn't everyone feel better now?
