In-joke

In-jokes are comedy elements, or in some cases, homages added to a production or a situation. The comedy comes from shared knowledge between a specific group such as co-workers, members of the same organization or people with a shared belief or knowledge of a shared situation.
There are many in-jokes that people have added to displays and scripts for Star Trek over the last 50 years. 
Examples include:
* the recurrence of the number 47
* various displays on okudagrams, and indeed the name okudagram itself 
* references in the Star Trek universe to other science fiction shows and movies
* references to real world facts about other Star Trek series (Camus II)
* the "sharing" of planets and species between Star Trek and other science fiction
* nicknames for production staff or crew making it into references within continuity (see: great bird/s of the galaxy) and so on.
* door labels
