Nuns at Rome's Convent of the Immaculate Conception have won the Pope's prestigious morality prize for the 100th year in a row.
They beat hundreds of other church groups after yet another successful year when not one single nun got pregnant, had an abortion or gave birth to a baby out of wedlock.
"How do the Sisters do it?" astonished reporters from the Vatican Times asked Reverend Mother as she received the winning gold trophy from the Pontiff.
"Well, we had some damned sensible advice from our Founder, Sister Marie Boniface," the senior nun explained.
"She told us that when it comes to contraception nuns should always use their head."
