Gus: I have a gun. It's loaded. Shut up.

Rose: You're a "Wong"?

Gus: Well, my mother was Irish.

Rose: And your father?

Gus: Wasn't.

Gus: From now on, the only person who gets to yell is me. Why? Because I have a gun. People with guns get to do whatever they want. Married people without guns - for instance, you - DO NOT get to yell. Why? NO GUNS! No guns, no yelling. See? Simple little equation.
