Ahh ya, that old romex! that stuff is messy as heck to work with as well..
I have seen that stuff all over here in my city, and the last I saw it installed
was in the late 70's or early 80's when me 'pops wired up the basement.. Have seen it in almost every colour too, I don't know the reason, probably different manufacturers, but shiny silver, dull grey, black, blue, green, brown and orange were common, and I have seen it in both copper and aluminum conductor... ( gotta love the 70's eh)!!

Oh yeah, gotta love the use of the cord!
Full marks for the person spending the coin using what looks like "SO" cabtire and not sacraficing a dollar store extension cord! [Linked Image]
