Once there were three blond who were all trying to figure out how to cross a river. They tried walking across, but it was much too deep. Stumped, they sat down and began to cry.
Soon, a kind fairy came along. When she saw their tears, she offered to give them each a wish if they would stop weeping.
The first man wished, "I wish I was smart enough to figure out how to cross this river."
The fairy turned him into a man with light-brown hair. He swam across the river.
The second man wished, "I wish I was even smarter than that."
The fairy turned him into a man with dark-brown hair. He built a rowboat and rowed across.
The third man wished, "I want to be smarter then any man alive!"
The fairy turned him into a woman and he walked across the bridge.
