Scarlett: "But you are a blockade runner."
Rhett Butler: "For profit, and profit only."
Scarlett: "Are you tryin' to tell me you don't believe in the cause?"

Rhett Butler: "And you, Miss, are no lady."

Scarlett: "Rhett, Rhett... Rhett, if you go, where shall I go? What shall I do?"
Rhett Butler: "Frankly, my dear, I don't give a damn."

"I can't go all my life waiting to catch you between husbands."

"A cat's a better mother than you."
