Diane: Excuse me, Marvin? Listen to me. You're having trouble with your marriage, aren't you? Believe me, I understand how you feel.
Marvin: Nobody understands how I feel.
Diane: I do!
Marvin: Oh, sure, sure! You ever been in love with trash?
Diane: Yes! This disgusting pile right here.
Marvin: Sam?
Diane: Exactly. He's trash. But l... I love him with all my heart.
Marvin: Why?
Diane: Because... I've got to. You tell me. Why do you love her? Because neither one of us can help it. But I'm asking you as a favor from one sucker to another, don't waste my fella.
