If you put your hands into two buchets and applied the current directly accross your body then it might be just a little risky though since trhe current would then be flowing accross your heart. I heard a similar story aabout a British University at which they were doing _OFFICIAL_ research into electric shocks. They wanted to find out how much current a person could *feel* (not to kill him). To do this they put a volunteer into a tank of water with an electrode on him and earthed the other end. They were going to start at 'negligible' voltage and gradually increase it untill he could feel something. With the first shock they killed him... -Pete French.
