[during the fight between the Robinsons and the pirates, the pirate chief raises a white flag]
Kuala, Pirate Chief: [calling up to the Robinsons] Kuala make talk! You hear?
Father Robinson: [calling back down] We hear you!
Kuala, Pirate Chief: [referring to Roberta AKA Bertie] You take boy belong Kuala. Give us boy, no more fight. You hear?
Father Robinson: You want the boy? You come and get him. We're ready for you, and you can put away your white flag.
Roberta 'Bertie': Maybe it would be better to agree.
Father Robinson: Don't worry. He wouldn't bargain with us if he thought he could beat us.
Kuala, Pirate Chief: Send the boy down the hill! Kuala take boy. Get plenty money. Nobody hurt. You hear?
[the Robinsons stand their ground; the chief puts the flag away]
Kuala, Pirate Chief: You make Kuala fight long time, then you die and Kuala take boy all the same!
[the fight between the pirates and the Robinsons resume]

[Reflecting on their island paradise]
Mother: It's wonderful for today, but what about tomorrow?

[trying to think of a way to get off the ship-wrecked boat]
Ernst Robinson: Why don't we put up a distress flag?
Father Robinson: Don't you think we look distressed enough? Ernst, anyone who sees a ship stuck on the rocks might possibly guess it's in trouble.
