Quote context

[...]

- Besides, I'm really after this terrific string. I'm working on a love nest for two. You know what I mean?

- Oh, I see. You have a girl.

- Well, not really. I mean, I haven't found Miss Right yet. But when I do, the whole world will hear us singing.

(SPLASHING)

- Excuse me. Pardon me.

- Well, you keep making all that noise and Dragon will hear you. If he hasn't already.

- Wouldn't you sing, too? I mean, if you felt... If you felt the call of the wild?

- I would... I would not if I knew there was a cat nearby.

- But she's out there. Somewhere. And when I find her, I'll feel it way down in my wishbone.

- What cat?

- Dragon. He belongs to Farmer Fitzgibbons. Look towards the house. See if you can see him.

- Come back down here. He'll see you for sure up there.
