Ready, Aim....

A blonde, a brunette and a redhead spy get caught behind enemy lines.

The enemy puts each of them against a fence to be shot.

The general orders his squad, "Ready. Aim."
The brunette spy is quick on her feet and yells, "TORNADO! TORNADO! TORNADO!"
The entire firing squad goes to the bunker to hide and waits for the tornado to pass. The brunette then unties her bondage and escapes. The redhead spy sees this and comes up with her own plan. The firing squad returns to kill the remaining two spies.
The general orders again, "Ready. Aim."
The redhead spy then shouts, "EARTHQUAKE! EARTHQUAKE! EARTHQUAKE!"
The enemy takes cover from the earthquake. The redhead spy then unties her bondage and escapes. The blonde spy is no dumby she gets an idea of her own. The firing squad returns to kill the last remaining spy.
The general orders once more, "Ready. Aim."
The blonde spy ready to run yells, "FIRE! FIRE! FIRE!"
