So my kid's tablet charger snapped off in the kitchen outlet last night, leaving the two prongs jammed in there with nothing to grab. Sat there staring at it for a good ten minutes before I trusted myself to touch it. First thing I did was kill the breaker for the kitchen circuit. Flipped it off, then plugged a lamp into the top socket to confirm it was dead before I went anywhere near the prongs. That part took two minutes and made the rest way less scary. Grabbed a pair of needle nose pliers from the garage, worked one prong loose with a little side to side wiggling, and the whole plastic chunk popped right out. Didn't even scratch the faceplate. The outlet itself looks fine, no scorching or melted plastic, so I reset the breaker and it's back in service.
Moral of the story is don't yank chargers out by the cord like my household aparently does. Bought a couple of those plugs with grippy sides the next morning.
