Why?

Geppetto: 

Now close your eyes and go to sleep.

Pinocchio: 

Why?

Geppetto: 

Everybody has to sleep. 

Figaro goes to sleep - and Cleo - 

and besides, tomorrow, you've got to go to school.

Pinocchio: 

Why?

Geppetto: 

Oh, to learn things and get smart.

Pinocchio: 

Why?

Geppetto: 

[starts to fall asleep] 

Because.

Pinocchio: 

Oh.
