- Bobby Brady: Geez, I can't wait to get started. Grand Canyon! Wow!
- Mike Brady: Well, it's not just the canyon, Bob. Now we can learn all about the Indian tribes that live there like the Havasupai, the Hopi, the Hualapai, the Navajo.
- Peter Brady: How'd they get such strange names?
- Mike Brady: Well, each name means something, Pete. Like Havasupai, for instance, means "Great People of Blue-Green Running Water."
- Bobby Brady: How about my name, Dad? Does Bobby mean anything?
- Peter Brady: Yeah. It means little man with great, big running mouth!
