A young Irish lad and two of his buddies are walking through the town, when the lad stops in front of the church and tells his friends to wait for him while he goes in for a quick confession. He takes his seat in the confessional and tells the priest that he has had premarital sex.
"Who was the girl?" asks the priest.
"I wouldn't feel right telling even you father," responds the lad.
"Was it Maggie O'toul?" asks the priest.
"No father."
"Was it Mary O'Donald?"
"No father."
"Then was it Becky O'Brien?"
"No father."
"You're not going to tell me are you lad?"
"No father."
"Well then say fifty hail Marys and never do it again" says the priest.
When the lad emerges from the church his buddies immediately ask him if he had to tell the priest who the girl was.
"No," responds the lad, "but I sure got some good leads."
