Define 'laugh' and 'cry'....

Most species experience pain, and react according to their nature. It may not seem like tears to us, but the emotional aspect is as real as it is to humans.

Most species experience at least contentment, and react according to their nature. Our jokes might not seem funny to them, but animals, at least, do have an equivalent to laughter.
