Dirty Duck... They made a soft porn animated film with a parody of Donald Duck in the 1970s. I think it was drawn in crayon on acetate cels! It was a such a wretched looking film but the creator had no budget! Even Bill Plympton films (which I generally like) are far more finished. They did a couple of adult animated features in the 1970s in the US including at least 2 Fritz the Cat features, Dirty Duck, a couple of Ralph Bakshi films, and the cycle climaxed (pardon the expression!) with the Heavy Metal feature film in 1981. Heavy Metal was easily the best of the "adult animated features." There's a sequence in Heavy Metal/1981 this is the inspiration for the feature film, The Fifth Element. It's so obvious The Film Element plagiarized it! Fifth Element arrived 16 years after the original Heavy Metal film.
I to once had a copy of this performance along with several others skits with Bobby the duck on a VHS tape BUT it was so good someone stole it from me at a 'girls night of comedy' we used to have back in the 90s'. So glad I found them here on the tube!!!I just love technology!
