Three blondes were walking through the desert when they found a magic genie's lamp.


After rubbing the lamp to make the genie appear, he said, "I will grant three wishes, one for each of you."


The first said, "I wish I were smarter."


So, she became a redhead.


The second blonde said, "I wish I were smarter than she is."


She became a brunette.


The third blond ordered, "I wish I were smarter than both of them!"


So, she became a man.
