"The order is twelve off with four hidden a-specs, the rules of Risk: The Game of Global Domination, Drop the Judge, stabbing theory, the N-word repeated for two minutes, and Opposite Day theory.

'Theory of Mind: Mind-Brain duality and why determinism is fucking retarded.' I'm glad your here. Now you can tell Jordan I'm not being immature and you can tell everyone that they're doing empathy to me wrong. Additionally, the weaponized schizophrenia is something you should really be concerned about AND... The lack of me getting credit and payment is getting dangerously child-murdery! So yeah..."
