Paddy walks into his local church and says to Father Murphy "I'd like to give you these for your collection".
He hands over an incredibly worn pair of old Y-Fronts
Father Murphy replies "Jesus, Joseph and Mary Paddy, what on earth makes you think I'd want your old Y-Fronts?"
Paddy says "Well father, I know that you have a fragment of the true cross and a knuckle bone of st peter in your collection of holy relics"
"Of course" Father Murphy replies, "but I still don't understand why I'd want your old pants Paddy?"
Paddy says "Well my wife Mary was putting the laundry away and didn't she say to me, Paddy - you need to get shot of these - these have got to be the holiest pants in Ireland..."
