A Blonde, a Brunette and a Redhead are against a wall to be executed by a firing line.

Each is given an opportunity for last words. The Redhead is up first: she points and screams "Tornado!" Everyone freaks out and in the commotion she gets away. The Brunette is second and catches on the the plan: she points and screams "Tsunami," fleeing in the confusion. The Blonde has worked out a similar strategy and, on her turn, yells "FIRE!"
