No there isn't, 12v is not enough to "jolt" a ball sack or any other part of your body. Maybe a tingle if the balls are sweaty. (I suppose they would be.) Make sparks by shorting the probes and cause burns, sure. But not the torture device everyone thinks thanks to cheesy movies.

The stuff you learn here, eh?

Call me elitist, but I think people who are wired to enjoy pinball are just a little more "on," a bit more "alive," slightly more in tune with reality and their place in it and up to the challenge of battling gravity and learning a few rules and developing real skills and improving their concentration and reaction times.

Most of the other 99.999% would rather sit on their asses and stare at screens (or else are struggling to survive, wondering where their next meal is coming from).

To have access to pinball and ignore it is the easy route, for getting into it would require an effort. Dullards.

Make sure you say something about how being good at pinball requires "finesse."
