“Anyhow,' one of the scientists was saying to another, 'there simply isn't room in the museum's Fishes Hall , so we've decided to pretend to the public that a whale is actually a mammal without any legs.

In my experience the public will believe just about anything, so long as you write it down on a little piece of card.”
