That’s a true story

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.
Kay Adams: …
Michael: …That's a true story.
