While in Las Vegas in Jan for the boxing, I was given a Stun Gun off one of the lads I had been doing security work with as he was going home.
Later that day I decided to have a play with it as I had never had one before. After dismantling it and finding the 9v batt that powered it I thought it cant give that bad a shock from one of those! So while sat in a chair I decided to shove my thumb between the two electrods and press the button. I was told I made a really funny grunting noise before coming round slumped in the chair.
My good god never try it, my arm was killing for days after, and you sure can get a shock that would drop an elephant from a 9V batt. Very funny though.
