Sorry, I couldn't help myself on this one.
Wayne the Painter
There was a tradesman, a painter called Wayne, who was very interested in making a penny where he could, so he often would thin down paint to make it go a wee bit further.
As it happened, he got away with this for some time, but eventually the Church decided to do a big restoration job including the painting of one of their biggest buildings.
Wayne put in a bid, and because his price was so low, he got the job. And so he set to erecting the scaffolds, setting up the planks, buying the paint and, yes, I am sorry to say, thinning down the paint with turpentine.
Well, Wayne was up on the scaffolding, painting away, the job nearly completed when suddenly there was a horrendous clap of thunder. The sky opened, the rain poured down, washing the thinned paint from all over the church and knocking Wayne clear off the scaffold. He landed on the lawn among the gravestones, surrounded by telltale puddles of the thinned and useless paint.
Wayne was no fool. He knew this was a judgment from the Almighty, so he got down on his knees and cried: "Oh, God! Forgive me! What should I do?"
And amidst the thunder and lightning, a mighty voice spoke...
"REPAINT! REPAINT! AND THIN NO MORE!"
