Heh. House I rented was built before ubiquitous electricity. At some point, someone slapped a fuse box on the outside of the back wall and drilled a bunch of 1" holes in said wall to pass wiring. House was built on piers, so they just dragged wires around to places where they wanted outlets, which were mostly planted in the floor. Not a ground wire on site. I have no idea how they got away with renting that out, but it's not like I called code enforcement, either.
