A man was walking through the desert had not eaten for days. He came across a church, went in, knelt at the alter and prayed, "Good God give me some food!" As if by magic, a lump of meat dropped at his feet. Overjoyed he ate the food.

He came back every day with the same request, and everyday he was rewarded until one day a hand dropped at his feet. Puzzled he looked up...

There was a leper painting the ceiling.
