Sharon was taken to the doctor because she was putting on weight. Her mother, a somewhat overbearing woman, told the doctor all about it, poor Sharon was not allowed to say a word despite being a young woman of 15 years.

After a long monologue from her mother about how it must be her glands, the doctor examined Sharon and was able to make the diagnosis.

"Well," said the doctor, "I'm afraid that the reason why Sharon is putting on weight is that she is PREGNANT."

"Nonsense," said Sharons mother, "you're wrong, you've obviously made a mistake. Such a thing is just not possible. Sharon would never do anything like that, she doesn't know anything about such things." Turning to Sharon she boomed at her daughter, "Isn't that so?" Poor Sharon could only shake her head in abject agreement.

The doctor said nothing. He just washed his hands, walked to the window and stared intently into the evening sky.

"Well, doctor, have you nothing to say? Are you just going to stare out the window? bellowed Sharons mum.

The doctor quietly replied that he was looking for something, because the last time that this had happened a new star had arisen in the East and three wise men on camels had come looking for the fortunate mother and child.
