Getting Something Valuable

A man got to heaven and asked if he could go back and bring something valuable to him. Permission was granted and while back on earth, he collected all the gold he could afford. Upon returning to heaven, an Angel asked him where he'd brought? The man showed the Angel all of the gold. The Angel responded, "Why did you bring a bunch of pavement up here?!" Rev 21:21 - "And the street of the city was pure gold, like transparent glass."
