A fellow from an indigenous far off place was visiting New York City. As he was peering from the top of a skyscraper's open-air observation deck, he asked his host, "I have heard of this word 'problem' but don't quite understand what it means."
The host said, "Well, if I held you by your feet over the edge there dangling you above the streets, then you would have a problem."
The indigenous guy thinks for a minute, then he says: "Well, if you pulled me back up, I wouldn't have a problem. But you would. And if you dropped me, and I died, I wouldn't have any problems at all. But you would."
