It is a physiological fact that laughter and tension cannot occupy the same space at the same time. For example, if you lifted a hundred-pound weight and someone told you a funny joke, you would drop the weight because the laughter diffuses the tension that allows you to lift the weight. This illustration translates into a good metaphor for the baggage people carry in the workplace—which often translates into interpersonal conflict. Approaching these conflicts with a self-deprecating sense of humor can help to diffuse the tension that prolongs the existing conflict.
