I used to believe that stepping on our (battery operated) scales would most certainly lead to death by way of electrocution if there was even so much as one drop of water on your body. Too many safety videos at school, I guess.
I freaked out one day when my mom stepped on the scale before she finished blow-drying her hair. I thought it was a fluke that she didn't get shocked and continued to manuever my way around the bathroom very carefully for years, making sure not to touch the scales after my bath.
