A woman takes her 16-year-old daughter to the doctor.
The doctor says "Okay, Mrs. Jones, what's the problem?"
The mother says, "It's my daughter, Debbie. She keeps getting these cravings. She's putting on weight, and is sick most mornings."
The doctor gives Debbie a good examination, then turns to the mother and says, - "Well, I don't know how to tell you this, but your daughter is pregnant - about 4 months, would be my guess."
The mother says, "Pregnant?! She can't be. She has never ever been with a man! Have you Debbie?"
Debbie says, "No mother! I've never even kissed a man, I'm still a virgin!"
The doctor walked over to the window and just stood there staring out of it.
About 5 minutes pass and finally the mother says, "Is there something wrong out there doctor?"
The doctor replies, "No, not really, it's just that the last time anything like this happened, a star appeared in the east and 3 wise men came over the hill. And there's no way I'm going to miss it this time!"
You have to give the doctor an 'A' for positive thinking.
