Yes, I actually think this sort of self-aware silliness (also hot dog sandwich, etc) could be looked at as kind of “koans” of rationality. Ultimately the goal might be to recognise that pure rationality is incompatible with the inherent nebulosity of applying “meanings” to the world, and to embrace that interplay!

Or more likely i’m overthinking it and they’re just a way to have a funny argument with friends.
