(I work in the walrus exhibit at the park answering questions about the animals. One of our four walruses has metal caps on her teeth because she scrapes them on the ground constantly.)

Guest: “Hey, I have a question about the walrus with the metal teeth.”

Me: “Ah, yes. That is an interesting story! See, she–”

Guest: “So, why is that walrus a robot?”

Me: “Sorry, what? A robot?”

Guest: “Yeah, that’s the only one with metal teeth. You can tell it is a robot. Why would you put a robot walrus in with the real ones? Or are they all robots?”
