     A lot of us lose life's tough battles by starting a frontal attack-when 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

Sam's being late-serious illness at home-he decided that this by-now-familiar excuse wouldn't work any

longer. His supervisor was probably already pacing up and down preparing a dismissal speech.

     Yes, the boss was. Sam entered the office at 9:35. The place was as quiet as a locker room; everyone

was hard at work. Sam's supervisor came up to him. Suddenly, Sam forced a grin and stretched out his

hand. "How do you do!" he said. "I'm Sam Maynard. I'm applying for a job, which, I understand, became

available just 35 minutes ago. Does the early bird get the worm?"

     The room exploded in laughter. The supervisor clamped off a smile and walked back to his office. Sam

Maynard 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 than people in any other forum.
