The coyote is a living, breathing allegory of Want.

“The coyote is a long, slim, sick and sorry-looking skeleton, with a gray wolfskin stretched over it, a tolerably bushy tail that forever sags down with a despairing expression of forsakenness and misery, a furtive and evil eye, and a long, sharp face, with slightly lifted lip and exposed teeth. He has a general slinking expression all over. The coyote is a living, breathing allegory of Want. He is always hungry. He is always poor, out of luck, and friendless. The meanest creatures despise him, and even the fleas would desert him for a velocipede. He is so spirtless and cowardly that even while his exposed teeth are pretending a threat, the rest of his face is apologizing for it. And he is so homely! -so scrawny, and ribby, and coarse-haired, and pitiful.”

― Mark Twain, Roughing It
