-Michael: My father is no different than any powerful man, any man with power, like a president or senator.
Kay Adams: Do you know how naive you sound, Michael? Presidents and senators don't have men killed.
Michael: Oh. Who's being naive, Kay?
-[Tessio brings in Luca Brasi's bulletproof vest, delivered with a fish inside]
Sonny: What the hell is this?
Clemenza: It's a Sicilian message. It means Luca Brasi sleeps with the fishes.
-Michael: Well, when Johnny was first starting out, he was signed to a personal services contract with this big-band leader. And as his career got better and better, he wanted to get out of it. But the band leader wouldn't let him. Now, Johnny is my father's godson. So my father went to see this bandleader and offered him $10,000 to let Johnny go, but the bandleader said no. So the next day, my father went back, only this time with Luca Brasi. Within an hour, he had a signed release for a certified check of $1000.
Kay Adams: How did he do that?
Michael: My father made him an offer he couldn't refuse.
Kay Adams: What was that?
Michael: Luca Brasi held a gun to his head, and my father assured him that either his brains or his signature would be on the contract.
-Don Corleone: [to Michael] So, Barzini will move against you first. He'll set up a meeting with someone that you absolutely trust, guaranteeing your safety. And at that meeting, you'll be assassinated.
Michael: All right. This one time I'll let you ask me about my affairs.
Kay Adams: Is it true? Is it?
[Kay smiles and walks into his arms]
Kay Adams: I guess we both need a drink, huh?
[Kay goes to the kitchen to fix a drink, but sees Peter Clemenza, Rocco Lampone and Al Neri enter Michael's office]
Clemenza: Don Corleone.
