My mom once was getting ready for work and I hear a pop and hear my mom yelling. I go in and her necklace fell off the dresser; a "dust buster" wall wart was plugged in back there and it fell across the prongs, shorting it out.

This is why you always mount outlets with the grounding pin facing up!

... it was an ungrounded plug... Plus it was a chain, so it'd drape across all 3.

TBH, in the house I mount them ground down, but under cabinets or in the garage/shop or etc I mount it ground up.
