What is community? Perhaps it is just the place you live: as in "the community pool." But, community should be more than that, right? It is the intentional joining together of people (and objects) because they share something; and, hopefully, what they share is more than a zip code. Community is about belonging, interconnectivity, closeness, at least according to Nye in "Famous."
The speaker, who is clearly an adult, demonstrates the interconnectedness of the circle of life by talking about being kind to old men and children.
Nye is pointing out how corrupt our idea of fame is. The people we think of as famous couldn't be farther away from us, and what should really be famous is right close to home.
