"Bill Clinton is F*&%$D up!!!" joke

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 am
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 been married a long time. She's
a wonderful wife but she's never offered much excitement in the
bedroom, so I used to fool around with women a lot. Matt is actually
your half-brother, and I'm afraid you can't marry him." Chelsea was
heart-broken.
After eight months she eventually 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.
"Robert is your half-brother too, honey. I'm awfully sorry about
this." Chelsea was furious!
She finally 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 what he
says, dear. He's not really your father."
