Whenever this topic comes up I always find myself thinking "why not?"

We know humans are animals, and as far as we can tell, toilet humor is universal across cultures. Animals aren't as intelligent as humans, sure--but does anyone think that poop jokes require a lot of intelligence to get?

I feel like the history of studying animal cognition can be thought of as long process of us just getting over how special and unique we think we are. First it was problem-solving vs. pre-programmed instincts, then it was "man, the tool user", then it was language, and now sense of humor? Well why not?

I wanna say 'we think'* parrots have a sense of humor and I'm pretty sure we attribute 'play' as a motive for various crow behaviors so it seems pretty reasonable to assume they might have something we'd recognize as a sense of humor.

* 'we think' as in various pop-sci articles, so obviously apply your necessary skepticism filters.

Not sure if humor or legitimate vengeance. In a group it's important to punish individuals infringing on your sense of entitlement ;)

Anyway, it's impressive that the bird managed to connect so many dots correctly and creatively play an inter-species conflict.
