True Romance-Sicilian Talk scene

The following is a scene from one of my favourite movies- True Romance. It's also written by my favourite writers, Quentin Tarantino, who has brought simple yet effective dialogue to the movies he works on.

In this scene Dennis Hopper's character (retired Police Officer) squares off with Christopher Walken's character (Sicilian Mafioso)  via witty back and forth dialogue about the truth of his (Walken's) origins. Even though Hopper's fate is obvious in the presence of Walken's grim character, Hopper makes sure he wins the debate and goes out with a (literal) bang.
