Three women are about to be executed.One's a brunette,
One's a red head , and one's a blonde.Two guards bring the
brunette forward.  The executioner asks if she has any last
requests .She says no, and the executioner shouts, "Ready...
aim..." Suddenly the brunette yells,'Earthquake !!" Startled,
everyone looks around and she manages to make her escape.
The angry guards then bring the redhead forward.The
executioner asks if she has any last requests. She says no, and
the executioner shouts, "Ready... aim..." The redhead then
screams, "Tornado!!" Again,everyone is startled and look
around. She, too, escapes execution..By this point, the blonde
had figured out what the others had done.The guards bring
her forward. The executioner asks if she has any last requests.
She also says no, and the executioner shouts, "Ready... aim...
The blonde shouts, "Fire!!"
