Read it through once

“You can call it anything you want to, and be right. It is a fish, for it lives in the river half the time; it is a land animal, for it resides on the land half the time; it is an amphibian, since it likes both and does not know which it prefers; it is a hybernian, for when times are dull and nothing much going on it buries itself under the mud at the bottom of a puddle and hybernates there a couple of weeks at a time; it is a kind of duck, for it has a duck-bill and four webbed paddles; it is a fish and quadruped together, for in the water it swims with the paddles and on shore it paws itself across country with them; it is a kind of seal, for it has a seal's fur; it is carnivorous, herbivorous, insectivorous, and vermifuginous, for it eats fish and grass and butterflies, and in the season digs worms out of the mud and devours them; it is clearly a bird, for it lays eggs, and hatches them; it is clearly a mammal, for it nurses its young; and it is manifestly a kind of Christian, for it keeps the Sabbath when there is anybody around, and when there isn't, doesn't. It has all the tastes there are except refined ones, it has all the habits there are except good ones.
