How is a pig like a bottle of ink?

A pig and a bottle of ink can be compared metaphorically in that both can represent something that is often overlooked or underestimated. Just as ink can be a powerful medium for expression, a pig is often associated with various cultural symbols and can represent abundance or prosperity. Additionally, both can evoke strong reactions; ink can stain and create messes, while pigs can challenge societal norms regarding cleanliness and aesthetics. Ultimately, both embody the idea that beauty and value can be found in unexpected places.
