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?"

"You did that, Father."

"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 they met again.

"Well now, Mrs. O'Donovan," said the Father, "how are you?"

"Oh, very well," said she.

"And tell me," he said, "have you any little ones yet?"

"Oh yes, Father. I've had three sets of twins, and four singles - ten in all."

"Now isn't that wonderful," he said "And how is your lovely husband?"

"Oh," she said, "he's over in Rome to blow that bloody \\candle out!"
