Brain: We could learn! There are lots and lots of books out there that have something to do with Australia, and we could read them and listen to The Waifs and Aboriginal music and think the thinky thoughts about water and deserts and colonialism and magic and the rest of this worldbuilding stuff.
Brain: And then it would be years until we had time to deal with Sampo again.
Me: Back to work, you.
