I might try that after a couple beers!!! Seriously though, most people don't understand these things are high voltage, but extremely low amperage(like a stun gun). It's amperage that kills you. That's why the 120volts in the electrical outlet in your house can kill you but the 10,000 volts in...
To test my fence I kick off my sandals, grab a long blade of grass or weed. Wet it (little spit will do the trick) and hold it on the wire. Seriously. You will get a little tickle to let you know it is working.
