Aliens wanted to study the psychology of human beings by experiments,so they selected China,Japan, Germany and United States, from each of which they caught two very handsome young men and a very beautiful young woman,settling them on four desert island respectively,and offering them sufficient foods and other living necessities. This was desigened to find out what would happen when two men and one woman lived together.
One year later,the aliens came to the island where the Chinese were living, and they found that the three people kept a common friendship among them, because they were still missing their lovers.On the island where the Germans were living, there were only one man and one woman living together,with the third gone, because he had been killed in a duel. Contrary to the case of the Germans, there was one more person on the island where the Japanese were living ,but the two men shifted responsibilities on each other and quarreled endlessly, because the Japanese are always unwilling to admit what they have done. What happened among the Americans made the aliens dumbfounded:The two men addicted themselves to homosex, and the woman was left out in the cold!
