Once upon a time there were three princes. There was the stupid prince, the filthy prince and the slightly orange-coloured prince.

One day, to everyone's big suprise, they all had to go out into the world and do something. What it was they didn't know, for their father had not told them. "Ye get out there now," he had said, "ye lousy freaks, and do something that shows ye deserves this kingdom. One of ye is going to get it — the one of ye doing the best thing."

And out they went.

...

And then, to everyone's even greater suprise, they returned.

They stood before the king, tense, but not drained in sweat, and he watched them with tired and for the moment curious eyes. "What have ye done?" he asked.

"I ate a frog," the stupid prince said. The king was not impressed. "It made me see stars," the prince added, with a strange smile.

"I bathed in a muddy frog pond," the filthy prince said. The king was not impressed. "It made me cleaner," the prince added, with a sad countenance.

Before the slightly orange-coloured prince had the chance to say what he had done, the king said, "Ye have just been behind the stables, haven't ye?" The princes nodded. "I should have known," the king said, shaking his head in a sad kind of way. "What about ye, sligthly orange-coloured prince? What have ye done?"

"I did nothing," the slightly orange-coloured prince said. And he won the kingdom.
