- The Fonz: Just one question: what's an adorable little lady like you doing on a volcano like this?
- Anna Olsen: I am searching for my father. He believes this volcano is the entrance to a lost civilization at the center of the Earth.
- The Fonz: [Mr. Cool shakes his head in disbelief] Aiaiai wha?
- The Fonz: Yeah, well, you know, fathers can be like that some time.
- Richie Cunningham: Hey Fonz, Cupcake found the trouble.
- Cupcake: So we can spin off any time, without any outside help.
- Ralph Malph: And get back to Milwaukee without any more detours.
- The Fonz: Sorry Ralph, but there has been a slight change of plan, we're taking Anna here to the center of the Earth.
- Ralph Malph: You hear that, Rich? Hahaha, the center of the Earth. What a sense o' humor!
- Richie Cunningham: I don't think he's joking, Ralph.
- Ralph Malph: Well that must be why I'm not laughing.
- [starts crying on Richie's shoulder]
- Richie Cunningham: Oh, Ralph...
- Ralph Malph: [facing a prehistoric seamonster] Please don't eat me! I'm outta shape, you wouldn't like me. Eat them!
- Richie Cunningham: Spoken like a true coward, Ralph.
- Anna Olsen: My father!
- Professor Olsen: My child! My goose!
