- Harriet Oleson: Nels, I don't think it's right to be taking one child's word over another.
- Nels Oleson: Why not? You've been doing it ever since Nancy came here.
- Harriet Oleson: That is incorrect!
- Nels Oleson: So is this homework. Problem #3 is incorrect on Willie's paper, also on Nancy's. #7 is incorrect on both. #11 is incorrect on both. Coincidence? No!
- [turns to Nancy]
- Nels Oleson: If you're going to choose someone's homework to copy, you need to choose someone who's good in math. Your brother isn't.
- Willie Oleson: Nobody's jealous of Nancy. Nobody wants to be in the pageant because nobody likes her!
- Harriet Oleson: Willie!
- Willie Oleson: It's true! She's mean and she's nasty, nastier than Nellie ever was. She knew Belinda was in the ice house when I closed the door. She wanted her to get sick so she could be the star of the pageant.
- Nancy Oleson: That's a lie!
- Willie Oleson: No, it's the truth!
- Harriet Oleson: Willie, how dare you make up a story like that. Go to your room right now!
- Willie Oleson: I didn't expect you to believe me. I'm only your son!
- Harriet Oleson: Well, she's not gonna get away with it anymore! I am gonna put my foot down!
- Nels Oleson: Well, it's about time.
- Harriet Oleson: Yes! She'll be sorry. She'll go to bed without any dessert tonight.
- Nels Oleson: That's the punishment?
- Harriet Oleson: You think it's too harsh?
- Harriet Oleson: That's right! I am your mother! And you won't
- [Throws ball]
- Harriet Oleson: ... Lie to me
- [Throws ball]
- Harriet Oleson: ... AGAIN!
- [Throws ball and hits target]
- Nancy Oleson: [to Willie] You ripped my homework paper!
- Willie Oleson: That's right, I did. And I'm gonna rip your lips off if you don't stop lying!
- Nancy Oleson: Mother! Mother!
- Nancy Oleson: [to Albert after finding out the truth about the mermaid booth] You let me out of here now!
- Albert Quinn Ingalls: Nope. You wanted to be the mermaid.
- Nancy Oleson: You lied to me!
- Albert Quinn Ingalls: You're the last one to talk about lying. All I said was that it would be the most popular booth. Look around. Did I lie?
- Nancy Oleson: [to Willie] How do I look?
- Willie Oleson: Like a 50-pound guppy.
- Nancy Oleson: I hate you, you know.
- Willie Oleson: Yeah, I know, but I don't care. I'm used to it. I had another sister once, too.
- Laura Ingalls Wilder: [voice-over] Nancy stayed in the dunk tank for the rest of the day and a lot of people said she was a good sport to do it. Oh, we knew she'd still be nasty, but she'd be better, because she knew folks cared enough about her not to let her get away with things she shouldn't. So think about that the next time your folks punish you.
- Nels Oleson: Now!
- Harriet Oleson: No!
- Nels Oleson: Now!
- Harriet Oleson: No!
- Nels Oleson: NOW!
- Harriet Oleson: Now!
- Willie Oleson: [about Nancy] . It's like having Nellie as a sister all over again. Only *this* time, I can beat her up!
