- But, Rocko, that's the way things are.

- I want to fly. I'm gonna fly, and no one's gonna stop me. I'm flying. Flap them. Flap them. Flap them.

- Don't laugh. Nobody laughs at Rocko the Rockhopper.

- That's funny. You see, I expected you to tell me something big, really stupendous. You know, like hopping up the slopes of Mount Everest or something, you know.

- Waldo?

- Yeah. He's... He's...-Who's Waldo?

- Waldo is a short little penguin back in my rookery.

- Yeah? Really?

- Yes, really.
