Billy Clanton: [as Doc Holliday is drunkenly playing a somber piece on the saloon piano, Clanton speaks, just as drunkenly] Is that "Old Dog Trey? Sounds like "Old Dog Trey."

Doc Holliday: Ah, yes. Well, this happens to be a nocturne.
Billy Clanton: A which?
Doc Holliday: You know, Frederic fucking Chopin.
