Humor

"My guess is that there aren't a hundred top-flight professional comedians, male and female, in the whole world. They are a much rarer and far more valuable commodity than all the gold and precious stones in the world. But because we are laughed at, I don't think people really understand how essential we are to their sanity." - Groucho Marx

Humor is one of the most important tools of the human spirit. (DU)
