I would spend my Death Row years formulating an antidote for the lethal injection, and I would drink it just before being injected. I would get my hands on a knife or some sort of sharp object before being injected. I would refuse a 'last meal', and when they injected me, I would fake my death, then jump up out of nowhere and cut all of their throats. I would then shove the bodies in a closet and steal one of their uniforms. I would use their keys to make my way out of the building, and then use one of their cars to get home.
Then I would take all of their wives out for my 'last' meal.
