You can marry any one of them
你可以跟他们中的任何一个结婚

One day a girl brings home her boyfriend and tells her father she wants to marry him. After talking to him for a while, he tells his daughter she can't do it because he's her half brother. The same problem happens again four more times! The girl starts to get pissed off. She goes to her mom and says, "Mom... What have you been doing all your life? Dad's been going around laying every maiden in the town and now I can't marry any of the five guys I like because they have turned out to be my half brothers!!!"
Her mom replies, "Don't worry darling, you can marry any one of them you want, he isn't really your dad."

一天，一个女孩把男孩子带回家见父亲，说要跟这个男孩结婚。她父亲跟男孩谈了一会之后，对她说她不能嫁给这个男孩，因为男孩跟她其实是同父异母的兄弟。之后，女孩又认识了另外四个男孩并一一带回家见父亲，请求父亲同意他们结婚，但结果都是一样，这些男孩竟然跟她都是同父异母！女孩真的是被气坏了。她跟母亲说，“妈，你这一辈子到底是怎么过的？爸爸在镇上到处胡搞，现在我都谈到第五个男孩了，但现在一个都不能嫁，因为他们最后都是跟我一个爸爸”！
女孩说完，她母亲回答说，“亲爱的，不用担心，你可以跟他们中的任何一个结婚，你爸爸其实也，也不是你的亲爹”。
