The elephant, although a gross beast, is yet the most decent and most sensible of any other upon earth. Although he never changes his female, and hath so tender a love for her whom he hath chosen, yet he never couples with her but at the end of every three years, and then only for the space of five days.

Who hears the fishes when they cry?

A good dog, sir, deserves a good bone.

Be a good animal, true to your animal instincts.
