Susanna: I do not need to be insulted by someone who buys art because it matches his bedspread.

Frasier: Oh, I have Book-Lover's Discount.
Clark: Ah, we don't accept that.
Frasier: Independent Booksellers?
Clark: No.
Frasier: Uh, Bibliophiles? Dewey Decimal Discount? Dust Jacket Gang?
Clark: I'm sorry. We do have our own card. It's $25.
Frasier: $25? For a little card?
Clark: You get 50% off all purchases.
Frasier: Very well. How much will I save today?
Clark: The discount starts with your next purchase.
