Three blondes are stuck on a Turks and Caicos island, and one finds a magic lamp. They rub it, a genie pops out, and gives them each a wish.
The first blonde says, "I wish I were 10% smarter so I could get off of this island!" She then turns into a redhead and swims off the island.
The second sees what happens and says, "I wish I were 25% smarter so that I could get off this island!" She then turns into a brunette, makes a raft from trees and sails off.
Finally, the third blonde says, "I wish I were 50% smarter so I can get off this island." She suddenly turns into a man and walks across the bridge.
