Frieda: [she comes in and sits down in front of Schroeder's piano where Lucy usually sits] Schroeder, I think it's disgraceful the way Lucy bothers you, and she's always asking everybody "Why does he always have to play that stupid piano?" I think that's terrible.
[pause]
Frieda: Incidentally, why DO you always have to play this stupid piano?
Lucy van Pelt: [comes in and sees her] What are you doing here?
Frieda: Who wants to know? Maybe I just like music.
Lucy van Pelt: [sits down beside her] Do you like Beethoven?
Frieda: What?
Lucy van Pelt: If you're going to hang around here, you've got to like Beethoven.
Frieda: All right, but I'll just have a small glass.
[Schroeder stops playing when he realizes what she just said, then angerly pulls the piano out from under both of them]
Lucy van Pelt: You blew it, kid.
