Three blonde girls are on an island, and they are much too far away from land to swim. They find a genie on the island who offers them each one wish. The first girl says, "I wish I was smart enough to get off this island!" So the genie makes her a redheaded girl, she cuts down a tree, makes it into a boat, and proceeds to row off the island.
The next girl says, "I wish I was even smarter than her so I don't have to do so much manual labor!" So she turns into a brunette and makes a sailboat and lets the wind take her off the island.
The final girl says, "I wish I was smarter than both of them!" So she turns into a man and takes the bridge.
