Fake art gallery

The extras on the TV show are walking through the art gallery. They are background characters, and the art is too.

Yet, the producers wanted the extras to have a good time: The fake art gallery filled with scenes from previous episodes from the show and plaques with in-jokes.

This did not need to happen.
This did not improve the scene.
This did not make the show directly better.

Yet, the show was made great.
