There once was a poor fisherman and his wife who lived in a pigsty by the seaside.  The fisherman goes fishing one day and comes across a fish who was actually an enchanted prince.  The fisherman went home to tell his wife about the fish and his wife insisted he go back and ask the fish for something.  First she sent the husband to ask for a snug cottage.  They were granted the cottage.  The wife wasn’t happy enough with the cottage so she then sent her husband to ask for a castle.  The wife continually isn’t happy with what she is granted and continues to send the husband to ask for better/more glorious things.  In the end the husband and wife return home to the original pigsty they began with because the wife was too greedy and upset the enchanted fish.
