One Sunday morning Chelsea burst into the living quarters at the White House and said, "Dad! Mom! I have some great news for you! I'm getting married to the greatest hunk in Washington. He lives in Georgetown and his name is Matt.
After dinner, the President took Chelsea aside "Honey, I have to talk with you. Your mother and I have married for along time. She's a wonderful wife but I fool around with women a lot. I think that Matt might be your half-brother, and I'm afraid you can't marry him."
Chelsea was heart-broken. After eight months she started dating again. A year later she came home and very proudly announced, "Robert asked me to marry him! We're getting married in June."
Again her father insisted on another private conversation and broke the sad news. "I think that Robert might be your half- brother too, honey. I'm awfully sorry about this." Chelsea was furious! She decided to go to her mother with the news. "Dad has done so much harm. I guess I'm never going to get married," she complained. "Every time I fall in love, Dad tells me the guy is my half-brother."
Hillary just shook her head. "Don't pay any attention to him, dear. He's not really your father."
