Mark Twain's fictional character Tom Sawyer was given the job of whitewashing a picket fence. The weather was mild and he was just a kid and he got tired or bored after painting a foot or two of fence. As pals came by to see what he was doing, they visited and Tom became aware of a way that he could get the fence painted with almost no effort on his part, and maybe a bit of gain. Before you know it, his friends were almost fighting for a turn at painting the fence.
It's been many many years since I read Tom Sawyer, but as I recall, the fence was whitewashed in record time - maybe with two or three coats.
