I also read Carmine Persico didn't like to be called "the snake" and preferred "junior". No idea why, "the snake" isn't "rat" or "cockroach", imo it's a cool nickname, poisonous snakes are deadly and anyway it's an animal that represents being cold and sly and being able to dodge dangers or weasel the way out of difficult situations.

Willie Marfeo to Henry Tameleo:

1) "You people want a loaf of bread and you throw the crumbs back. Well, fuck you. I ain't closing down."

2) "Get out of here, old man. Go tell Raymond to go shit in his hat. We're not giving you anything."
