My dad used to check for spark by pulling plug wires bare handed. When he would get zapped, he would barely flinch and say "Oh, that one bites a bit..." I am much more sensitive to shocks, and have been blown right out from under the hood a few times when zapped! All in all not a recommended way to check for spark...

One time I was trouble shooting my nephew's motorcycle and he kicked it over hard while I had ahold of the spark plug wire. Man, I chased that little sh-t around the house three times till I tired out, with him laughing the whole time. That was 25 years ago and he still talks about it.
