Quote context

[...]

- No good, hmm? Well, I guess we'll have to move right on then to plan B.

- Plan B?

- What's that?

- As I see it, Santa doesn't want to go because nobody cares, right?

- Right.

- He thinks there's no Christmas spirit, no goodwill. Right?

- Right.

- So all you have to do is go down there and find some example of Christmas spirit left over from last year.

- Scout up some goodwill and show him some proof that somebody cares. Right?

- Right.

- Santa will change his mind, and presto, Christmas is on again.

(ELVES CHEERING)

- Now, make sure you don't get lost.

- Lost?

- Vixen's made the trip. Haven't you, dear? She'll take you. No problem.

- Just hurry along and gather up enough proof to change Santa's mind and we can get on with Christmas as usual.
