You can marry any one of them
你可以跟他們中的任何一個結婚

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，一個女孩把男孩子帶回家見父親，說要跟這個男孩結婚。她父親跟男孩談了一會之后，對她說她不能嫁給這個男孩，因為男孩跟她其實是同父異母的兄弟。之后，女孩又認識了另外四個男孩并一一帶回家見父親，請求父親同意他們結婚，但結果都是一樣，這些男孩竟然跟她都是同父異母！女孩真的是被氣壞了。她跟母親說，“媽，你這一輩子到底是怎么過的？爸爸在鎮上到處胡搞，現在我都談到第五個男孩了，但現在一個都不能嫁，因為他們最后都是跟我一個爸爸”！
女孩說完，她母親回答說，“親愛的，不用擔心，你可以跟他們中的任何一個結婚，你爸爸其實也，也不是你的親爹”。
