"Star in the East" joke

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 Debbie is pregnant - about 4 months, would be my guess. ”

The mother says, “Pregnant?! She can’t be, she has never ever been left alone with a man! Have you, Debbie? ”

Debbie says, “No mother! I’ve never even kissed a man! ”

The doctor walked over to the window and just stares out it. About five 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 three wise men came over the hill. I’ll be darned if I’m going to miss it this time! ”
