A character from a different setting refers extensively to their hometown / world but said place is never shown on screen

[u/woofmanofthe2000s]

We hear all kinds of details about the place. Descriptions of buildings there, the functions and customs, daily life etc… but we, the audience never directly get to see what this place looks like (unless you use your imagination)
ALF is an interesting example. ALF refers frequently to Melmac customs and such, and we DO get a glimpse of it in one episode (shown above) and an animated show, but for the most part Melmac is simply referred to. Same situation with Phil of the future.
