Several international businessmen were on a conference cruise when the ship began to sink. "Go and tell those fellows to put on life jackets and jump overboard," the captain directed his first mate.

　　A few minutes later the first mate returned. "Those guys won't jump," he reported. "Take over," the captain ordered, "and I'll see what I can do."

　　Returning moments later, he announced, "They've gone."

　　"How'd you do it?" asked the first mate.

　　"I used psychology. I told the Englishman it was the sporting thing to do, and he jumped. I told the Frenchman it was chic(时髦); the German that it was a command; the Italian that it was forbidden."

　　"And how did you get the American to jump?"

　　"No problem," said the captain. "I told him he was insured!"
