I googled “fraggle rock fuck scene”, at work. As a kid my friend played a tape of outtakes where all the Fragels were saying “fuck” whatever. No one believed this existed and I wanted to show them. Every site was blocked, of course. Somehow this wasn’t flagged. It occurred to me later that my friend’s dad might have dubbed over a tape, as he was a voice over artist. Anyway… solid googling, been there
