shower fun time

so victim gets in the shower. person locks/blocks them in the shower. victim does not know they are locked in. let victim get all wet and fill the shower up with a bit of water. (before victim gets in shower) hook up a stun gun, or some other low voltage torture machine to the drain of show (which is usually metal). so, victim is stuck in shower, soaking wet, naked, water at the bottom of the tub, turn on electricity, watch the fun.
