A Catholic Confessing (joke)

There was this catholic teenager who goes to confession, and after
confessing to having an affair with a teenage girl is told by the
priest that he cannot forgive this terrible sin if the boy doesn't
tell who the girl is.

The boy says  "Aw father, I promised not to tell"

"Was it Mary Particia, the Butcher's dayghter?"
"Come on father, no it wasn't and I wont tell"
"Was it Mary Elizabeth, the printer's daughter?"
"No, and I still won't tell"
"Was it Mary Francis, the baker's daughter?"
"No, it wasn't and I really can't tell you who."
"We;;, son, I have no choice but to excommunicate you for six months."

The boys friend meets him afterwards outside the church and asks him
how it went:

"Well, I got six months on the outside, but three good leads!"
