Dirty Duck is a fictional character created by underground comix artist Bobby London.
While promoted under the abbreviated title Dirty Duck, the film has no connection to London's character or comics.
The cartoon strips planned to run underneath O'Neill's "Odd Bodkins" never saw print.
John Bagley's San Francisco-based Company & Sons published The Dirty Duck Book #1 in December 1971.
Duck is a wealthy and elderly gentleman with a lecherous streak and a sharp (if sardonic) wit.
