One day, a dad and his son were walking along the beach when they came across what looked like a lump of wood sticking out of the sand. The dad thought it was just a piece of driftwood, but his son had a different idea. He picked it up and examined it closely, soon realizing that it was actually a valuable piece of ambergris – a rare substance produced in the digestive system of sperm whales. The dad was amazed at his son’s discovery and grateful for his keen eye. They took the ambergris home and later sold it for a significant sum of money, making their beach walk that day a truly profitable one.
