Quote from Coach Mellor in Jimmy 5 is Alive
Barry: So is it possible? Can we unfilm what I taped over? Coach Mellor: Absolutely. All we gotta do is pop that tape into the VCR, hit record and rewind at the same time, and it will unrecord the top layer of video. Barry: Duh. The answer was in front of me the whole time. Coach Mellor: To the nerd hole!
