It's kinda old news now but I still love searching for made-up idioms.

> "You can't get boiled rice from a clown" is a phrase that plays on expectations and the absurdity of a situation.

> The phrase "never stack rocks with Elvis" is a playful way of expressing skepticism about the act of stacking rocks in natural environments.

> The saying "two dogs can't build an ocean" is a colloquial and humorous way of expressing the futility or impossibility of a grand, unachievable goal or task.

People get to make up idioms and AI's don't?

They're just playing games. Of course that violates the 'never play games with an AI' rule, which is a playful way of expressing that AIs will drag you down to their level and then beat you over the head with incompetence.
