Archbishop Gilday: The Pope is gravely ill. Until he recovers, I am powerless.
B.J. Harrison: What if he dies?
Frederick Keinszig: Then, as you Americans say, all bets are off.

Kay Corleone: You know, Michael; now that you're so respectable, I think you're more dangerous than ever. I liked you better when you were just a common Mafia hood.
Michael Corleone: If someone is going around this city saying, "Fuck Michael Corleone," what do we do with a piece of shit like that? He's a fuckin' dog.
Joey Zasa: Yes, it's true. If someone were to say such a thing, they would not be a friend. They would be a dog.
