The first expedition to Alpha Centauri had finally returned. The leader of the expedition, Captain Jones, was making his report to his superior.

“So, Jones, did you find any indigenous life?”

“Yes sir. Intelligent life, in fact. And what’s more, they were almost completely identical to humans, except for one thing.”

“Almost? What do you mean?”

“Well sir, they have one less joint in their arms.”

“I see. So, I suppose you could say that…”

“Yes sir, The natives are wristless.”
