Let's not be too quick to blame the human race for everything. A great many species of animals became extinct before man ever appeared on earth.

The Dodo never had a chance. He seems to have been invented for the sole purpose of becoming extinct and that was all he was good for.

The Earthworm plows the whole world with his tunnels, drains and aerates the earth… If you ever buy any land, be sure it has plenty of Earthworms toiling and moiling all day so that you can sit down and relax.

We all make mistakes, but intelligence enables us to do it on purpose.

Galvani was mistaken about the amount of electricity in frogs, but he had some good ideas, too, for the galvanometer is named in his honor, and you don't have galvanometers named after you merely for making a mistake about a frog.

The Love bird is one hundred percent faithful to his mate-who is locked into the same cage.

Frogs will eat red-flannel worms fed to them by biologists; this proves a great deal about both parties concerned.
