T-Rex: Robyn bought a haunted mansion on the hill, and it was haunted by several spooky ghosts: a woman in white, a man in chains, and a knight in rusted armour.
T-Rex: They returned every night to haunt her for years!
T-Rex: Judging by their clothes, they all died centuries ago. They rattled their chains, they slammed doors, they threw plates around, but one thing they never did, Robyn noticed, is EAT. Ghosts consumed no energy, but could still haunt houses indefinitely. Robyn realized that besides being paranormal, they were also paraENTROPIC: ghosts were outside the laws of thermodynamics!
Utahraptor: They're doing work without costing energy anywhere!
T-Rex: EXACTLY. Free energy, Utahraptor!
T-Rex: Now, ROBYN'S old-time ghosts refused to ride bicycles hooked up to generators, but before long she'd moved to France and rented houses belonging to deceased Tour de France champions, who took to the bicycles quite easily. And that, dear reader, is how our post-scarcity utopia was created.
Off panel: I thought screaming cursed blood skulls did that in your last story.
T-Rex: This one's way more sustainable. You get ghosts for free, just by dying!!
T-Rex: DUDE, IT'S LITERALLY IMPOSSIBLE TO AVOID.
