Once upon a time there was a married couple who were always arguing. One day, the wife had had enough and decided to take a walk to cool off. As she walked, she noticed a small frog hopping across her path. She bent down to pick it up and the frog said, "If you kiss me, I'll turn into a handsome prince."

The wife smiled, gave the frog a kiss, and - sure enough - the frog turned into a handsome prince. He thanked her for the kiss and asked her what she wanted as a reward. The wife thought for a moment, then said, "I want you to argue with my husband for me for the rest of our lives."

The prince agreed and the couple went home. From that day forward, the husband and the prince argued about everything and the wife was able to relax and enjoy her marriage.
