Mrs. O'Donovan was walking down O'Connell Street in Dublin, and coming in the opposite direction was Father O'Rafferty.
"Hello," said the Father, "and how is Mrs. O'Donovan? Didn't I marry you two years ago?"
She replied, "That you did father."
The priest asked, "And are there any little ones yet?"
"No, not yet Father," said she.
"Well, now, I'm going to Rome next week, and I'll light a candle for you."
"Thank you, Father." And away she went.
A few years later he ran into Mrs. O'Donovan's husband. "Well, now, Mr. O'Donovan," said the Father, "how are you?"
"Oh, very well," said he.
"And tell me," He said, "have the O'Donovans had any wee ones yet?"
"Oh yes, Father. Three sets of twins, and four singles -- ten in all."
"Now, isn't that wonderful," he said "And how is your lovely wife?"
"Oh," he said, "she's gone to Rome, to blow out that candle!"
