Three Blondes And A Genie

There are three blondes on an island, and they can't find their way off. Also on the island is a genie. The genie says that he will grant them each one wish. So the first blonde wishes to be smart so she can get off the island. So the genie turns her into a red head, and she swims off the island. The second blonde wishes that she could be smarter than the first one, so the genie turns her into a brunet and she takes the boat off the island. Finally, the last blonde wishes that she could be smarter than the first and second one combined, so the genie turns her into a man and she takes the bridge off the island.
