Dirty Duck (1974)
[in the desert]
Willard: Say, how did you come to be a duck?
Duck: Well, I was a turtle for a while, but that wasn't going anywhere. Then my mother gave me the chance to be a duck, and I sort of flowed from there...
[while the Duck is talking, a caricature of Frank Zappa rises like the sun over the horizon]
Willard: Oh, Eddie, you have GOT to be kidding.
Flo & Eddie: Liz, Mary or Louise - They'll get down on their knees. Or, Sydney the dyke, Uh, what would you like? We're here to please. June, Cindy or Jeanine Or, all three might be a scene. It's all up to you, a Negro, a Jew For you to screw.
