If I haven't fired you yet, it's because I'm still firing your mom in bed.
Not with a police tazer, but I have personally licked one end of a battery pack while touching the other that totaled a whopping 117 volts of direct current. Knocked the daylights outta me. My scientific urges were then satisfied :L
It's a good thing I wasn't dumb enough to try it when I completed the battery pack; I got it up to around 250 volts. Just a bunch of 9v batteries connected in series. My goal was to make a welder, lol
