ACT 1. Description
The pomists agree on the most boring object in the room. Each pomist writes four lines to describe that object, being as plain in their description as possible. Pass this to the left.
ACT 2. Translation into opposites.
The pomists take this pome then translate every word into its opposite. They fold over the first version and pass the paper to their left. This repeats until the every pomist gets their original.
