- Hello, my dears! We have a wonderful show today.

- We have Mr. Van Zandt from the Sierra Club, and he's going to bring some animals that are endangered species.

- Do you know what that means, poppets?

- Wait a minute.

- Did you say puppet?

- Oh, no, dear. Oh, it's Kovacs. Welcome, Kovacs.

- Hi, guys.

- Did you say extinction? Did you smell something? Something stinks?

- I'm not talking about something smelling bad. I'm talking about extinction. That means when there's no more of a particular animal.

- Oh, my gosh.

- Doesn't that make you a little mad?

- It makes me very mad.

- Well, tell people about it.

- I'm mad. You know why? Because next it's the chimps. That's right. There are fewer chimps in the world than there used to be.

- Doesn't it make you mad that humans are playing your parts in movies?

- Ooh, Cheetah, Planet of the Apes. Who gets his role? Roddy McDowell. I'd do better than that.
