Down and Dirty Duck
From Zappa Wiki Jawaka
"Down and Dirty Duck" (1975) is an American X-Rated animated film directed by Charles Swenson and produced by Roger Corman. The film was intended to cash in on the success of the similar adult animated movie "Fritz the Cat" (1972) by Ralph Bakshi.
Aside from starring a few of Zappa's musicians "Down and Dirty Duck" also references Zappa's 200 Motels (1971). In one scene the duck (Howard Kaylan) protests: "You can't do this to me! I was at Woodstock in '69. I saw "200 Motels"! I know who I am!" Another scene Willard (Mark Volman) asks the duck how he became a duck. He answers that he "used to be a turtle, but that wasn't too happening", so he got "some advice from his mother" and "just sort of flowed (a pun on Flo from Flo & Eddie) from there." During their conversation a huge caricature of Frank Zappa rises like the sun over the horizon. Hereupon Willard says: "Oh, Eddie, you have GOT to be kidding", in reference to Zappa's song Eddie Are You Kidding?.
