- I have to go down to the electronics store to pick up a tube for the Bat-sound analyzer. We can't make a move without it. I should be back in a hour.

- Okay.

- One, two, three. Sorry. That's all right, you'll get the hang of it. You're doing just fine, fine.

- I don't think I'll ever learn to dance. I just don't have any natural rhythm.

- Balderdash. Ha, ha. You'll pardon the expression, now

- I'm a little out of breath. Could we take a break?

- Certainly.

- Very nice place you have here, Master Grayson. Very homey.

- 14 bathrooms, 18 bedrooms.

- How many entrances are there to the place?

- Three.

- Why are you asking all these questions about the house? You seem more interested in the layout of Wayne Manor than giving me a dancing lesson.
