"For being such an exemplary married couple and for being loving to each other for all this time, I will grant you each a wish."
The wife answered: "Oh, I want to travel around the world with my darling husband." The fairy waved her magic wand and - hey presto - two tickets for the Carnival Destiny appeared in her hands.
The husband thought for a moment: "Well, this is all very romantic, but an opportunity like this will never come again. I'm sorry my love, but my wish is to have a wife 30 years younger than me."
The wife and the fairy were deeply disappointed, but a wish is a wish. So the fairy waved her magic wand and - hey presto! - the husband became 92 years old.
The moral of this story: Men who are ungrateful blighters should remember that fairies are female.
