A mother and her daughter were at the gynecologist's office. The mother asked the doctor to examine her daughter. "She has been having some strange symptoms and I'm worried about her," the mother said.
The doctor examined the daughter carefully and then announced, "Madam, I believe your daughter is pregnant."
The mother gasped, "That's nonsense! Why, my little girl has nothing whatsoever to do with men." She turned to the girl. "You don't, do you, dear?"
"No, mumsy," said the girl. "Why, you know that I have never so much as kissed a man!"
The doctor looked from mother to daughter, and back again. Then, silently he stood up and walked to the window, staring out.
He continued staring until the mother felt compelled to ask, "Doctor, is there something wrong out there?"
"No, Madam," said the doctor. "It's just that the last time anything like this happened,
a star appeared in the East and I was looking to see if another one was going to show up."
