There are three blondes washed up on an island. Suddenly a fairy appears and offers to grant each one 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 ravishing redhead.
The redhead 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.
