Scooby gang did it first though. Definitely reversed the polarity of something in nineteen seventy something... Or maybe it was nineteen eighty something. Had curly wires, whatever it was. Oooh oohh, Dr Who reversed the polarity of the neutron flow in the sonic screwdriver. I think that was in the 70's too. So maybe that was first - he was relatively young then of course. Oh yes, also, Rocky Horror Show (not the Picture), reversing polarity occurs in song!
Ok, you didntt' want to know that, did you?
Did anyone else fancy Velma?
