“Ooh, that’s a nice fish, evolution.”

“Oh, thanks! I’m pleased.”

“What is it called?”

“This one’s a pearlfish.”

“Lovely. And what does it eat?”

“Little invertebrates, that kind of thing.”

“Delightful. And where does it live?”

“Inside the anus of a sea cucumber.”

"Oh, for Christ’s sake.”

“What? It’s a fine place. Safe, sheltered, just the right size for the fish to squeeze in.”

"And you were doing so well for a minute there, too.”
