- Well, young lady, what's your name?
- Mine? Kris Kringle. I'm Santa Claus.
- Oh. You don't believe that, do you?
- Mm-mmm.
- You see, my mother's Mrs. Walker, the lady who hired you.
- But I must say, you're the best-looking one I've ever seen.

- That's because it's real, just like I'm really Santa Claus. Oh, go ahead. Pull it.
- All right, folks. Don't crowd. You have all day to see Santa Claus. Now, children, behave.
- This way, please. Get back in the line there.
