He looks up to heaven and says "God, could you answer a question for me?"
"Of course, my son," says God, "what would you like to know?"
"God, what is a million years to you?"
"Well," says God, "a million years to me is as a second."
"Hmm," says the man. "I guess I understand. So what is a million dollars to you then?"
"My son," God says, "a million dollars to me is as a penny."
"Hmm," says the man. He goes back to praying, but after a little while he looks up again.
"God," he asks, "can I have a penny?"
"Sure," God says. "Just a second."
