Derek, the painter, often would thin his  paint so it would go further. So when a local church decided to do some deferred maintenance, Derek was able to put in the low bid, and got the job. As always, he thinned his paint way down with turpentine.

One day, while he was up on the scaffolding, the job almost finished, he heard a horrendous clap of thunder, and the sky opened.

The ensuing downpour washed the thinned paint off the church and knocked Derek off his scaffold onto the lawn among the gravestones and puddles of thinned and worthless paint.

Derek knew this was a warning 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 thundered, “REPAINT! REPAINT! AND THIN NO MORE!”
