“The human race has only one effective weapon, and that is laughter.” -Mark Twain

If you want to impress somebody, make them laugh. If you want to connect with someone new, make them laugh. If you want to get a raise from your boss, make him laugh. If you want to take yourself out of a completely miserable situation, make yourself laugh. And if you want to change the world, make the world laugh. What’s the easiest way to make someone laugh? Tell a joke.
