Death Row

A blonde, a brunette, and a redhead are all awaiting execution by firing squad.

The brunette goes first, but just before the shots are fired she yells, "Flood!" The executioners flee and the brunette gets away.

The executions regroup and the redhead is selected next. But just before the shots are fired the redhead yells, "Tornado!" The executioners again scramble and the redhead escapes unscathed.

The executions regroup once more and prepare the blonde for the firing squad. But just before the shots are fired the blonde, thinking of herself as clever as the other two women, yelled, "Fire!"
