The Blonde Spy.

Three female spies -- a brunette, a red-head, and a blonde -- had been captured and were awaiting execution. The enemy dictator was nostalgic and had ordered an old-fashioned execution: death by firing squad.
Needless to say, the three spies wanted to survive... but they needed a plan. The red-head spoke up. "I have an idea," she said. "Follow my lead."
As it happened, the red-head was first up against the wall.

"Do you have any last words?" the dictator asked.
"No," she replied.
"Very well," said the dictator as he turned to his soldiers.
"Ready.... Aim...."
"TORNADO!" yelled the red-head, pointing behind the troops.
The gunmen all turned around, and she escaped!

The brunette and blonde saw this and got the idea. Next it was the brunette's turn. The dictator marched her up to the wall in front of his soldiers.

"Do you have any last words?" he asked.
"No," she replied.
"Very well," said the dictator as he turned to his soldiers.
"Ready.... Aim...."
"TIDAL WAVE!" the brunette yelled out, pointing.
The gunmen all turned around, and she escaped, too!

The dictator was becoming frustrated, but now it was the blonde's turn. He marched her to the wall in front of his troops.

"Do you have any last words?" he asked, suspiciously.
"No," she replied.
"Very well," said the dictator as he turned to his soldiers.
"Ready.... Aim...."
"FIRE!" said the Blonde
