Quote context
[...]
- Why, they've never swept this room. You'd think their mother would...
- Maybe they have no mother. Then they're orphans. That's too bad.
- I know! We'll clean the house and surprise them. Then maybe they'll let me stay.
- Now, you wash the dishes. You tidy up the room. You clean the fireplace. And I will use the broom.
(BIRDS CHIRPING AND WHISTLING)
- Just whistle while you work and cheerfully together we can tidy up the place.
- So hum a merry tune... It won't take long when there's a song to help you set the pace.
- Oh, no, no, no, no! Put them in the tub.
- When hearts are high, the time will fly, so whistle while you work.
