- The Thief: I, I have found this. It's a plan of the church at Tolino. I discovered it in a very old manuscript.
- Mario Forni: How do I know you didn't make this yourself?
- The Thief: Do I look like a thief?
- Mario Forni: Yes. You stole this, didn't you?
- The Thief: Out of need, Signor, out of need.
- Mario Forni: I'm sorry I don't do business with thieves.
- The Thief: I''m a poor scholar. With eleven children. All with the whopping cough.
- Mario Forni: I see you've been doing your bit toward the population explosion. However, I might be induced to give a small donation. But you must understand, if I give you money that makes me an accessory. And I am a businessman, my dear scholar. And, of course, it's those eleven poor children - they do worry me.
- Mario Forni: How much do you want for that?
- The Thief: A million Lire. I want a million Lire.
- Mario Forni: I thought you didn't believe in marriage.
- Madame Rinaldi: I don't. But you make me believe in my own disbelief.
- Mario Forni: I think I know what you mean.
- Madame Rinaldi: And like all other men, you think you're absolutely irresistible.
- Mario Forni: Oh, not any more. I used to be, you know, but nowadays I find that I have to fight a little harder. What were we talking about?
- Madame Rinaldi: Mohammedan.
- Aguesta, Town Banker: We pay to commit sins, then we have to pay to uncommit them. It goes against the grain.
- Mario Forni: [after their car loaded with treasure rolls over the cliff into the ocean below] Hey, do you know how to skin dive?
- Madame Rinaldi: No. But I'll learn.
- Mario Forni: I'm unprincipled enough not to have any principles worth anything. But I've never killed anybody. But somehow, some way, I feel I've killed her.
- Aguesta, Town Banker: You've been a great mayor. I voted for you myself.
- Mayor Pablo: I voted myself for myself.
- Mario Forni: Now, who should we talk about - you or me?
- Madame Rinaldi: You.
- Mario Forni: No, I don't think so. Let's talk about you. I know all about me.
- Madame Rinaldi: And I know all about me, so the conversation is already over.
- Beppo: You know when I get to New York, perhaps I will send for you.
- Pia Pacelli: Why is it always New York with you - the big town? I come from a big town - Venice. I know how it is in the city. And in Venice, when the tide is low, it stinks and there's garbage in the canals. Ach! I'll never go back to live in a slum.
- The Bishop: There was a miracle, Pia. You see, child, the things of God that are marvelous are to be believed in. But sometimes reason destroys, because it proves to the reasoning mind only that which is reasonable, and leaves out all that is marvelous. But all is well, child. All will be well. The miracle was in your own faith. Keep that faith, my dear. Keep it always. With God's everlasting blessing.
