- Micky: You don't understand, we're not thieves, Maria. Ah, mamma. I mean mom, eh...
- Mama Maria: Nonsense, the urge to steal is basic. We are al thieves at heart.
- Davy: Where did she get that idea?
- Mike: She stole it.
- Mama Maria: If they don't drop that vulture in five minutes, it's curtains for you!
- Peter: Oh, for a minute I thought you were gonna kill me.
- Mama Maria: He's going through a stage.
- Davy: Oh, I'm realy glad to hear that.
- Mama Maria: Marco's sullen moods only last 3 years!
- Mama Maria: Marco, one word please. You know the plan: each one of you will knock them out, drug them, drag them, and then tie them up. But Marco, promise me one thing: No rough-house.
- Micky: Sir, this is an emergency. Don't look startled. Just look straight ahead. Pretend we are having a normal conversation. Good. Now, after I tell you this, I want you to walk calmly out of this place and call the police. Sir, there are thieves here that are going to steal the Maltese Vulture.
- Yugoslavian Guest: Ah, Yugoslavia, grosni polyo pussmulnjitsi.
- Party guest: [admiring the Maltese Vulture] Oh, how beautiful. How could anything so beautiful come from such an ugly bird?
- Madame Rantha: Oh, you've met my husband?
- Mama Maria: He's a very tricky young man. You can tell he's a thief. It's written all over his face.
- Mama Maria: [Peter has 'theif' written on his forehead] A good thief, but a bad speller.
- Davy: Well Maria, we're certainly glad you've turned over a new leaf.
- Mama Maria: Yes, you boys have shown us that my boys can make a faster dollar in showbusiness.
- Marco: And with as little talent, too.
