Mrs. Sugarman: Oh, did I ever tell you the time, when my late husband sent me...
Sebastian: Yes, you already did, Mrs. Sugarman.
Mrs. Sugarman: Oh, I did?
Sebastian: Right after we played backgammon, Mrs. Sugarman.
Mrs. Sugarman: Oh! We played backgammon?
Sebastian: Uh huh. You beat me three times.
Mrs. Sugarman: I did?
Sebastian: Yup. Then I fucked your daughter.
Mrs. Sugarman: Excuse me?
Sebastian: I said, would you care for some water?
Mrs. Sugarman: No, thank you.
