Excerpt
Humor is the secret weapon of the nonfiction writer.
If you trying to write humor, almost everything you do is serious.
One strong editorial cartoon is worth a hundred solemn editorial.
The writer must find some comic device—— satire, parody, irony, lampoon, nonsense—— that he can use to disguise his serious point.
Today the outlandish becomes routine overnight. The humorist is trying to say that it's still outlandish.
The targets will change from week to week, but there will never be a dearth of new lunacies and dangers of the humorist to fight.
Humor aren't as urgent, but they help us to look at far older problems of the heart, the home, the family, the job and all the other frustrations of just getting from morning to night.
Humor is not a separate organism that can survive on its own frail metabolism. It's a special angle of vision granted to certain writers who already write good English.
Don't search for the outlandish and scorn what seems too ordinary; you will touch more chords by finding what's funny in what you know to be true.Finally, don't strain for laughs; humor is built on surprise, and you can surprise the reader only so often.
There's no law that says humor has to make a point.
今天这章讲幽默。看的时候就一直在想《笑之大学》。当年看完去豆瓣上翻影评，看到这样一句话：“喜剧创作必须抱持严肃的态度与目的，否则连当哗众取宠的笑料资格都没有。”幽默背后的，才是作者真正想表达的啊_(:зゝ∠)_不过要注意不要解读过度，有时候可能真的只是个玩笑。
