A Roman Catholic priest is on his way to Rome when he runs into an old childhood friend.
“My goodness, Mary!” he says. “How have you been?”
“Oh, could be better,” she says. “My husband Robert and I have been trying to have children for fifteen years, but we are barren.”
“I’m so sorry,” says the priest. “I’m on a pilgrimage to Rome, and I promise to light a candle for you in the great cathedral.”
Mary thanks him, and after chatting a little longer, they part ways.
Five years later, the priest is eating dinner when there’s a knock at his door. He opens it, and to his surprise, it’s Mary’s husband, Robert.
“I’m so glad I found you!” he exclaims. “Remember that candle you lit for Mary, years ago? Well, Mary and I now have two sets of twins and a set of triplets — and I just found-out she’s pregnant with quadruplets!”
Robert then hands the priest an all-expenses paid ticket to Rome.
