When I encounter a substance dualist, this is how I mock their position.

Consciousness arises from physically undetectable, yet also indestructible, mind-stuff, which wasn’t present until humanity reached its current evolutionary phenotype, and which, despite not interacting with the body, both determines and is affected by its actions and is also perpetually localized to each individual person until they die at which point it goes to a non-localized location that also can’t be detected.
Also, like in the comic that comes from, my interlocutor can’t tell that I’m making fun of their position.
