How Fishy? (by Jasper Fforde)

(Something happened before, leading to this conversation between two SpecOp Officers)

"What do you think?"

"Fishy," said Bowden. "Very fishy. How could something like Cardenio (note: a long-lost manuscript by Shakespeare) turn up out of the blue?"

"How fishy on the fishiness scale?" I asked him. "Ten is a stickleback and one is a whale shark."

"A whale isn't a fish, Thursday (note: the female Officer's first name)."

"A whale shark is--sort of."

"All right, it's as fishy as a crayfish."

"A crayfish isn't a fish," I told him.

"A starfish, then."

"Still not a fish."

"A silverfish?"

"Try again."

"This is a very odd conversation, Thursday."

"I'm pulling your leg, Bowden."
