Painting A Church Joke

One day, a city decided to do a big restoration job on the painting of its Roman Catholic cathedral. Jack the painter put in a bid, and because his price was so low, he got the job.
And so he set to erecting the trestles and setting up the planks, and buying the paint and, yes, I am sorry to say, thinning it down with turpentine.
Well, Jack was up on the scaffolding, painting away, the job nearly completed when suddenly there was a clap of thunder, and the sky opened. The rain poured down, washing the thinned paint from all over the cathedral and knocking Jack clear off the scaffold to land on the lawn among the gravestones, surrounded by tell-tale puddles of the thinned and useless paint.
Jack was no fool. He knew this was a judgment from the Almighty, so he got on his knees and cried: "Oh, God! Forgive me! What should I do?"
And from the thunder, a mighty voice spoke... "Repaint! and thin no more!"
