A woman had been dating a doctor for a short while when she became
pregnant. The couple didn't know what to do.  About nine months later,
just about the time she was going to give birth, a priest went into the
hospital for a prostate gland infection. The doctor told the woman, "I
know what we'll do. After I've operated on the priest, I'll give the
baby to him and tell him it was a miracle."

"Do you think it will work?" she asked the doctor. 

"It's worth a try," he said.

So the doctor delivered the baby and then operated on the priest.
After the operation he went in to the priest and said, "Father, you're
not going to believe this!"

"What?" asked the priest. "What happened?" 

"You gave birth to a child!"

"But that's impossible!" cried the priest.

"I just did the operation," insisted the doctor. "It's a miracle!
Here's your baby."

About fifteen years go by, and one day the priest realizes that he must
tell his son the truth. One day he sits the boy down and says, "Son, I
have something to tell you. I'm not your father."

The son said, "What do you mean, you're not my father?"

The priest replied, "I'm your mother. The archbishop is your father."
