Pappyism: Early to bed and early to rise is the curse of the working classes.
Jack: (about Bart) I think you ought to know this fellow's cheating you.
Bret: Of course he is. It's his deal.
Bret: (to Bart) In the bright lexicon of youth, there is no such word as can't.
Bret: That blonde, stupid look is deceptive, isn't it? You've got something up that Brooks Brothers sleeve of yours. You're planning to use me, aren't you?
Jack: Now you're beginning to think like a Vandergelt. Shrewd.
Bret: What makes you think you can buy me?
Jack: My dear fellow, I don't want to buy you. I simply want to rent you for a while.
Bret: Why are we here?
Jack: You're here to gamble. Myself, I never do.
Lydia: (about Jack posing as Bret) He's not society?
Bret: (posing as Jack) He's barely humanity.
Mrs. Mallaver: You could do far worse than marrying Mr. Lucious Benson.
Lydia: Not without a lot of thought and effort.
Bret: I'm not supposed to die for that $1,000 a week, am I?
Jack: I wouldn't let you do a thing like that. What sort of monster do you think I am?
Bret: (to Lydia) You know if it weren't for your manners no one would know you came from Philadelphia.
Bret: What's wrong with money?
Lydia: The people who have it. Usually they have very little else.
Bret: I thought I knew you, Van. Not smart I said but he does have a certain low animal cunning.
Jack: Father, I've been doing a lot of thinking.
Vandergelt: You'd better take it easy until you get used to it.
Vandergelt: (to Jack) You're just like all your mother's people. No guts.
Bret: Van, you can't court girls the way you steal railroads.
Jack: You ever been married?
Jack: You ever steal a railroad?
Bret: Not yet.
Jack: Then shut up.
Bret: (after their ruse is discovered) What are you gonna do?
Jack: I think I'll go quietly upstairs and open a vein.
