Last night I was vacuuming the house. I reached the final room, plugged the vacuum in and the adventure began. The vacuum wouldn't start, since I knew there was a short in the wire I wiggled it as I always do and the vacuum started right up. A few seconds later I noticed an unusual vibrating sound. I looked at the plug and smoke was pouring out of it. !!! and I cut the vacuum cleaner off. To make a long story short once the plug was pulled out of the wall (being in there less than a minute) a prong was missing and the plug was black. Very odd. No more upright vacuum cleaner.
Here's a couple of hasty pictures I took. We had to kick the circuit off so my camera didn't recognize anything until the picture was taken, so they're a little blurry.
