So the doctor delivers the baby and then operates on the priest. After the operation he goes in to the priest and says, “Father, you’re not going to believe this.”
“What?” says the priest. “What happened?”
“You gave birth to a child.”
“But that’s impossible!”
“I just did the operation,” insists the doctor. “It’s a miracle! Here’s your baby.”
About fifteen years go by, and 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 says, “What do you mean, you’re not my father?”
The priest replies, “I’m your mother. The archbishop is your father.”
