One Sunday morning, William burst into the living room

and said, "Dad! Mom! I have some great news for you!I

am getting married to the most beautiful girl in town.

She lives a block away and her name is Susan. After

dinner, William's dad took him aside."Son, I have to

talk with you. Your mother and I have been married 30

years. She's a wonderfulwife but she has not offered

much excitement in the bedroom, so I used to fool

around with women a lot. Susan is actually your

half-sister,and I'm afraid you can't marry her."

William was heart-broken. After eight months he

eventually started dating girls again. A year later he

came home and proudly announced, "Diane said yes!

We're getting married in June." Again his father

insisted on another private conversation and broke the

sad news. "Diane is your half-sister too, William. I'm

awfully sorry about this." William was furious! He

finally decided to go to his mother with the news.

"Dad has done so much harm. I guess I'm never > going

to get married,"he complained."Every time I fall in

love, Dad tells me the girl is my half-sister." His

mother just shook her head."Don't pay any attention to

what he says, dear. He's not really your father."

A good one Kwiz A man knows his mother but fathers can be trickier
