A very rich man is going to die. God decides to send an angel to warn him. Upon hearing the news, the man asks if he can bring his money to heaven with him. After consulting God, the angel informs the man he may bring one suitcase full of anything he chooses. In preparation, the man fills his baggage with bars of gold. After death, he comes to the gates of heaven with his suitcase. Peter asks to see what's inside and the mans treasures are revealed. Puzzled, Peter asks him why he brought pavement to heaven.
