"How can I do now?" A young man who is going to get married complains to one of his friend, "I've changed my girl friend for many times, but no matter which one I took home, my mother just doesn't like her."
"Uh, that's easy." said his friend, "You just find someone like your mother, and that would be O.K.."
"Yes, I tried. But," said the young man, "it turned to be my father who doesn't like her then."
