Rufio uses adjectives to insult Peter Pan at the dinner table in front of the other Lost Boys. After some time, Peter Pan stands up for himself and replies with his own, creative insults. This is an excellent example of how powerful adjectives can be in language.
The President is scheduled to announce the landing of the Galileo V on Mars and broadcast some images from it. A writer from NASA's public affairs department wrote the announcement, but the President finds issues with it, most notably some redundant words and unnecessary adjectives (ex: "extremely unique"). The President tasks his writer to redo the announcement, and he states the rewrite eloquently.
