There are three blondes stranded 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 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.
