[Gastone brings some champagne for Mamita]
Gigi: Can I take a glass of champagne, Mamita?
Madame Alvarez: Have you lost your mind, Gigi? Of course not!
[heads towards the kitchen; Gaston quickly slides his glass over to Gigi]

[Gigi prepares for her night with Gaston]
Gigi: Say a prayer for me tonight / I'll need every prayer that you can spare / To get me by... Say a prayer / And while you're praying, keep on saying / "She's much too young to die..." "On to your Waterloo," whispers my heart / Pray I'll be Wellington, not Bonaparte... Oh, say a prayer for me this evening / Bow your head, and please stay on your knees / Tonight...

[playing cards]
Gaston Lachaille: And therefore, I win!
Gigi: And therefore... you lose!
Gaston Lachaille: You cheated! Where did you get that fourth ace?

[singing]
Gigi: I don't understand the Parisians / Making love every time they get the chance / I don't understand the Parisians / Wasting every lovely night on romance! Any time and under every tree in town / They're in session two by two / What a crime with all there is to see in town / They can't find something else to do! I don't understand how Parisians / Never tire of walking hand in hand / They seem to love it, and speak highly of it. / I don't understand the Parisians! When it's warm, they take a carriage ride at night / Close their eyes and hug and kiss / When it's cold, they simply move inside at night / There must be more to life than this! I don't understand the Parisians / Thinking love so miraculous and grand / But they rave about it, and won't live without it / I don't understand the Parisians!

[singing]
Gigi: What time tomorrow will we get there? / Can I watch you play roulette? / May I stay up late for supper? / Is it awfully awfully upper?
Madame Alvarez: Gigi, you'll drive us wild! / Stop, you silly child!
Gigi: Is everybody celebrated, / full of sin and dissipated? / Is it hot enough to blister? / Will I be your little sister?
Madame Alvarez: Gigi, you are absurd! / Now not another word! Gigi!
Gaston Lachaille: Let her gush and jabber, / let her be enthused! / I cannot remember / when I have been more amused!
Madame Alvarez: Stop it!
Gigi: The night they invented champagne, / it's plain as it can be / they thought of you and me. / The night they invented champagne, / they absolutely knew / that all we'd want to do / is fly to the sky on champagne / And shout to everyone in sight / that since the world began / no woman or a man / has ever been as happy as we are tonight!
Gaston Lachaille: The night they invented champagne...
[pops a cork]
Gigi, Gaston Lachaille: ...It's plain as it can be / they thought of you and me. / The night they invented champagne / they absolutely knew / that all we'd want to do / Is fly to the sky on champagne / and shout to everyone in sight
[pops another cork]
Gigi, Gaston Lachaille: That since the world began / no woman or a man / has ever been as happy as we are tonight!
[a cork is popped]

Honore Lachaille: The River Seine!
Gaston Lachaille: All it can do is flow.
Honore Lachaille: But think of wine!
Gaston Lachaille: It's red or white.
Honore Lachaille: But think of girls!
Gaston Lachaille: It's either yes or no, and if it's no or if it's yes! / It simply couldn't matter less!

Aunt Alicia: Did you work hard in school today? What did you study?
Gigi: History. Napoleon's defeat at Waterloo.
Aunt Alicia: How depressing. What else?
Gigi: English.
Aunt Alicia: English? I suppose we must. They refuse to learn French.

Aunt Alicia: Marriage is not forbidden to us, but instead of getting married at once, it sometimes happens we get married at last.

Gigi: [to Gaston] I'd rather be miserable with you than miserable without you.

Honore Lachaille: Did she send a note?
Gaston Lachaille: Obviously.
Honore Lachaille: Oh, good, good! Did you have to change the arrangements?
Gaston Lachaille: Don't be vulgar.
Honore Lachaille: Ah, well, she's a wonderful girl, Gigi. So young, so fresh, so vulgar. She's not sophisticated like most other woman are, but then what do sophisticated women have to offer? Nothing! They are boring, they have no surprises! But a liaison with someone like Gigi can last for months!
Gaston Lachaille: Good night. Good night!
