Camarel, I found the Genovese/Costello prison sit down to be the largest piece of fiction in Wolf's book.

You shit-kicking, stinky, horse-manure-smelling motherfucker you! If you ever get out of line over there again, I'll smash your fucking head so hard you won't be able to get that cowboy hat on. You hear me? Fucking hick. -Nicky (Casino)
