I don't remember whether there already was a thread about who the dumbest mobster is, but I think nobody (including Allie boy and Gotti Jr) could ever beat Rosario Borgio (put a bounty on every policeman's head after failing to bribe them) and Jack Licavoli (used stolen credit cards and exchanged price tags on pants in shops).

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."
