Spark Plugs.

Now I cant remember where i saw this, or if i did actually see this, but anyhow let me continue.
i was watching tv i think, where i saw in some show, the car they were driving had broken down. they tried several different things to start the car, including punching it. The gem in the whatsit however is how they actually got the car running again. Not jump leads. they used a Defibrillator.

yes, an electrical device that gets papped on the chest to batter the heart into working again.

i am stunned (not literally, because then i'd be well and truly fucked, wouldn't i?).

the moral and whatsit of the story is that if your car breaks down outside a hospital, jump up to the nearest Cardiac Geriatrics ward and nick the heartstart machine.
