"one night I saw Dally gettin' picked on by the fuzz, and he kept real cool and calm the whole time. They was gettin' him for breakin' out the windows in the school building, and it was Two-Bit who did that. And Dally knew it. But he just took the sentence without battin' an eye or even denyin' it. That's gallant."
