"Ooh, I want to travel around the world with my darling husband," said the wife. The fairy moved her magic stick and - abracadabra! - two tickets for the new QM2 luxury liner appeared in her hands.
Now it was the husband's turn. He thought for a moment and said, "Well, this is all very romantic, but an opportunity like this only occurs once in a lifetime, so 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 made a circle with her magic stick, and -abracadabra! - the husband became 92 years old.
