There are three blondes stranded on an island. Suddenly a fairy appears and offers to grant each of them one wish.
The first blonde asks to be intelligent. Instantly, she is turned into a brown haired woman and she swims off the island.
The next one asks to be even more intelligent than the previous one, 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 to become even more intelligent than the previous two.
The fairy turns her into a man, and he walks across the bridge!
