My dumbass made one by accident. Plugged it in, walked to the other end, picked it up my saw, "Shit. How did I throw the wrong end out here?" Whatever, we've all strung the extension cord backwards before. Here come the IQ test.
Walked to the other end of the cord, yanked it and threw that end back out into yard, plugged it in. Went back to my saw, "Oh for fuck's sake!"
