Quotes:
[first lines]
Frank Costello: I don't want to be a product of my environment. I want my environment to be a product of me. Years ago we had the church. That was only a way of saying - we had each other. The Knights of Columbus were real head-breakers; true guineas. They took over their piece of the city. Twenty years after an Irishman couldn't get a fucking job, we had the presidency. May he rest in peace. That's what the niggers don't realize. If I got one thing against the black chappies, it's this - no one gives it to you. You have to take it.
