Walter 'Monk' McGinn: [Pins Amsterdam to the wall] That's it, that's it! Tear my head off and destruct the world! Just like the rest of the stupid Irish in this country! That's why I never ran with your dad!
Amsterdam Vallon: Get off me you crazy bastard!
Walter 'Monk' McGinn: [Leans in and whispers a line of Gaelic. Then, in English] It means, 'If you're not strong you'd better be smart.' Now I don't know if you're being too clever or too dumb, but whichever it is just remember this much. For all his faults, your father was a man who loved his people.
[Releases Amsterdam and walks away]
