When I very briefly went to Sunday school at the age of about six or seven, they used to have a collection plate passed around. I asked what the money was for.
"Well, it might be for..." Mum thought about it. "It might be for mending the church roof."
I didn't say any more about it, but I was convinced that I knew now what was going on. After the service, the organist would melt down the pennies with the steam from the organ pipes (!) and cover the leaks in the roof with the hot metal. Even though I know better now, it's still a persistent image.
