There were three blondes stranded on an island. Suddenly a fairy appears and offers to grant each one of them a wish.
The first blonde asks to be intelligent. She is turned into a brown haired woman and swims off the island.
The second blonde asks to be even more intelligent than the first. So instantly she is turned into a black haired woman. The black haired woman builds a boat and sails off the island.
The third blonde asks the fairy if she can be even more intelligent than the previous two. The fairy turns her into a man and he walks across the bridge.
