What did the featureless ocean say to the featureless polar bear with no teeth or claws?
Nothing, they didn't need to speak. Their silent understanding of one another was all that was needed.
"You see, the joke is that the polar bear and ocean are featureless and thus have no mouths or features to speak. They don't need to communicate to understand each other. The reader has to assume that this is a relationship based off of mutual telepathy and emotional understanding. The meta-joke is that although there is no communication between the two figures, you as the reader assume there is a relationship based on common ground between the two of them.", said the featureless meta-joke explainer.
