Generally speaking, people like those who have a good sense of humor.
Sometimes a touch of humor might well enable us to win. Consider the case of a young friend of mine, who hit a traffic jam on his way to work shortly after receiving an ultimatum (最后通牒) about being late on the job. Although there was a good reason for Brian's being late—serious illness at home—he decided that this by-now-familiar excuse wouldn't work any longer. His boss was probably already pacing up and down preparing a dismissal speech.
Yes, the boss was, as Brian entered the office at 9:35. The place was as quiet as a locker room (更衣室): everyone was hard at work. Brian's boss came up to him. Suddenly, Brian forced a smile and stretched out his hand. "How do you do!" he said. "I'm Brian. I'm applying for a job, which, I understand, became available just 35 minutes ago. Doesn't the early bird get the worm?"
The room exploded in laughter. The boss clamped off a smile and walked back to his office. Brian had saved his job, with the only tool that could win—a laugh.
Humor is a most effective, yet frequently neglected means of handling the difficult situations in our lives. It can be used for patching up differences, apologizing, saying "no", criticizing, getting the other fellow to do what you want without his losing face. For some jobs, it's the only tool that can succeed. It is a way to discuss subjects so sensitive that serious dialog may start a quarrel. For example, many believe that comedians on television are doing more today for racial and religious tolerance (忍受力) than people in any other forum.
