People on Earth say to God, "one penny of your money is one million dollars in our money." God says, "agreed." Then the people say, "one minute in your time is a thousand years in our time." God says "agreed." Then the people say, "you wouldn't miss a few pennies, how about making us all millionaires." God reaches into his pocket and says, "just a minute."
A million years later (a minute in God's time) the pennies land on Earth.
A professor told me that joke many years ago. Marvin Southcott, I think it was. He taught industrial design at Western Washington University.
