— I've been comin' here for six years, and six years you been stickin' it to me. I wanna know how come.
— You don't wanna know.
— Yeah, I wanna know how come.
— You wanna know?
— I wanna know!
— Okay, I'm gonna tell ya! 'Cause you had the talent to become a good fighter, and instead of that, you became a leg-breaker to some cheap, second-rate loan shark.
— It's a livin'.
— It's a waste of life!
