Mrs. Dilber: Are you all right, Mr. Scrooge?

Ebenezer: [ecstatic] I... I don't know. I don't know anything. I never did know anything.

Ebenezer: [starts laughing]

Ebenezer: But now I KNOW that I don't know anything!
[begins to sing and clap his hands]

Ebenezer: I don't know anything!/ I never did know anything!/ But now I know that I don't know/ All on a Christmas morning!

[speaking again]

Ebenezer: Shall I stand on my head? I must stand on my head.
[He does so, and Mrs. Dilber runs out screaming]
