I have a couple; one was a couple of weeks ago where a makeup mirror reflecting the sun almost caught the house on fire
(8x10 glossy photos here)
Went on a warranty call to a new house years ago where the HO said there was no switch for the Jacuzzi. I trace down the wires in the attic to see where the switch was and find a receptacle installed in its place. I take out the receptacle, install a switch and it works fine. That?s when the HO decides to tell me that that receptacle never worked, but when his wife plugged a blow dryer into it, the Jacuzzi came on!!! That would have been nice to know before I crawled all over the attic.
Then there was the guy that was getting shocked while sitting on the throne, It turns out he had the bathroom wallpapered a few days earlier with a foil backed wallpaper. The paper hangers cut the wall paper then tucked it back in the box, touching the hot screw on a receptacle, making the whole wall hot! This was in the pre GFCI days. When he would reach for the TP, he would get a nice buzz.:-?
