Jokes that make one country laugh out loud are likely to leave another nation confused and silent. / But humor can also be very revealing，if not always funny. / After all jokes are often just another way of expressing anxieties, fears and even prejudices. / In Britain, / if you are successful or powerful, you will probably become the subject of a joke in a popular magazine. / This magazine has been poking fun at the great and the good in British life for the last 35 years, / and its victims admit to reading it and laughing with it. / One of the most enduring types of humor is satire. / This is the art of making fun of people in positions of power—politicians，celebrities and even royalty. / Satire is usually done by people who understand what is going on，/ who have links to people who are doing things. / That is the whole point of it.
