Once there was an old rich man who was afraid of dying and leaving all his wealth behind on earth. So, he took up the matter with God. He pleaded day and night to be able to take all his earthly possessions with him. Finally, God conceded. He said the man could take as much as he could fit in one suitcase. The old man immediately went out, bought a huge suitcase, sold all he owned and filled the suitcase with gold bars. Shortly after that, the old man died. Awkwardly dragging the big, heavy suitcase, he approached St. Peter at the Pearly Gates. St. Peter stopped him, asked him to open his luggage, and then told him he couldn't bring his gold bars into Heaven. The man was irate. "You don't understand," he said. "I got permission directly from God himself for this. He told me whatever I could fit into one suitcase, I could bring with me."St. Peter, shrugged his shoulders and simply said, "Fine with me. But we've already got plenty of pavement here."
