The Irish good Samaritan

A priest was preaching in a school in Ireland; his text the parable of the good Samaritan. As he went through the parable, he asked the children why they thought the priest and the Levite passed the injured man on the other side of the road, instead of going to help him.
One enthusiastic young boy put up his hand: "Because they could see he had already been mugged, Father".
