Shock them?
I say that because of a story my mom tells all the time. She had an old Hoover bagged vacuum that she got just before I was born. When I was about 18 months old, she'd pulled the couch away from the wall to vacuum. She made her way around the side of the couch and apparently I'd gotten behind it and was playing with the vacuum cord. All if a sudden, the vacuum stopped. So she went to the outlet to plug it back in, but it was still in the socket. She looked behind the couch and saw me passed out, cord across my body, and teeth marks in the cord. She didn't realize till the next day that my arm may have been broken from the fall after being electrocuted.
We had that vacuum for years, and one day at about 8 yrs old, I pulled some electrical tape away from a part of the cord and sure enough, there were my toddler-sized teeth marks. All that time I thought she was just messing with me, till I saw the proof years later...lol
