Play It Again, Charlie Brown1971

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.
