"Anyhow, there simply isnt enough room in the museums Fishes Hall, so weve decided to pretend to the public that a whale is actually a mammal without any legs. Its pathetically ridiculous-I mean to say, just look at the thing, its a gigantic fish if I ever saw one-but mums the word! In my experience the public will believe just about anything, so long as you write it down on a little piece of card."
