I first thought of
People think I'm abhorrent, but I'm just the first one they want to charge when there's been an attack!
I, for one, don't fancy thinking about life assistance devices. But when someone has a heart attack, you'll want to quickly charge the defibrillator to reanimate her.
I'm just a slave to the machine, and I'll die without ever having lived!
This gets quite dark, but fits a defibrillator's role from the point of view of the patient.
Your car wont start? Don't look at me. I'm not the AA.
You can't start a car with a defibrillator, even though it bears some similitude to crocodile clips.
