Quote #1
CHARLIE'S FATHER (VIA THE WILL): As for my home and all other property, real and personal, these shall be placed in trust in accordance with the terms of that certain instrument executed concurrently herewith.
CHARLIE: What does that mean, the last part, what does that mean?
LAWYER: It means that the estate, in excess of $3 million after expenses and taxes, will go into a trust fund for a beneficiary to be named in this document.
CHARLIE: Who is that?
LAWYER: I'm afraid I can't tell you that.
CHARLIE: Who controls the money? You? You control the money?
LAWYER: No. He's called a trustee.
When Charlie goes to the reading of his father's will, he learns that his father has cut him out of the money part of his estate, leaving him only the car that busted up their relationship and some rose bushes. As you might imagine, the very money-focused Charlie is not happy.
Quote #2
CHARLIE: He got $3 million, but he didn't get the rose bushes. I got the rose bushes. I definitely got the rose bushes.
As you might imagine, Charlie is super annoyed at his father's will. He doesn't yet know who this unnamed trustee is who got the balance of his father's fortune… but he's clearly not pleased to be saddled with the rose bushes while the money goes elsewhere.
Quote #3
CHARLIE: Does he know how much money he's been left?
DR. BRUNER: No. He doesn't understand the concept of money.
CHARLIE: He doesn't understand the concept of money. He's just inherited $3 million and he doesn't understand the concept of money? Well, that is f***ing poetic, don't you think?
Once Charlie has found out about Ray's existence/identity as the beneficiary of the trust, he's quick to pick up on the irony that Ray doesn't even really understand how money works—and now he has a boatload of it, while Charlie (who clearly thinks he'd be a better recipient for that cash) gets none.
