JO: Chickens!

DOCTOR: Greetings!

DOCTOR: All right, all right, all right, all right. We're friends.

JO: Try clucking.

DOCTOR: Jo, when you've travelled as much as I have, you'll learn never to judge by appearances. These creatures may look like chickens, but for all we know, they're the intelligent life form on this planet.

JO: They not only look like chickens, they are chickens. And what about this?

(The box underneath the chickens has a place name stenciled across it.)

DOCTOR: Singapore.

JO: The Acteon galaxy, you said, Doctor?

DOCTOR: Oh, Jo, do come on.
