There's just a certain amount of satisfaction that's missing from "not knowing." Having some type of high-voltage delivery mechanism tied to the spark plugs would be a neater trick. I don't mean the normal electricity that's delivered to them as the engine runs. Doh. I'm of course talking about someone getting the surprise of their lives when trying to touch plugs that otherwise seem harmless on a parked motorcycle. Just imagine the look on the crackhead's face when he wakes up in the morning on the side of the road with the splitting headache. Of course if he doesn't wake up, it's probably a good idea to get the motorocycle (and yourself) the hell out of there fast.
