<P> The climactic production number ridicules war by comparing nationalism to a minstrel show . One segment is a variant on the old Negro spiritual "All God's Chillun Got Wings" (and was reportedly considered for deletion for the film's DVD release, for fear of offending African Americans): </P> <P> They got guns, We got guns, All God's chillun got guns! I'm gonna walk all over the battlefield,' Cause all God's chillun got guns! </P> <P> Shortly after, during the final battle scenes, "rightfully (...) called the funniest of all of cinema", Firefly can be seen wearing a different costume in almost every sequence until the end of the film, including American Civil War uniforms (first Union and then Confederate), a British palace guard uniform, a Boy Scout Scoutmaster's uniform, and even a Davy Crockett coonskin cap . Meanwhile, the exterior view of the building they are occupying changes appearance from a bunker to an old fort, etc . Firefly assures his generals that he has "a man out combing the countryside for volunteers ." Sure enough, Pinky is wandering out on the front lines wearing a sandwich board sign reading, "Join the Army and see the Navy ." Later, Chicolini volunteers Pinky to carry a message through enemy lines; Firefly tells him, "(...) and remember, while you're out there risking life and limb through shot and shell, we'll be in here thinking what a sucker you are ." Thomas Doherty has described this line as "sum (ming) up the Great War cynicism towards all things patriotic". </P> <P> The melodramatic exclamation "This means war!" certainly did not originate with Duck Soup, but it is used several times in the film--at least twice by Trentino and once by Firefly--and would be repeated by Groucho in A Night at the Opera and A Day at the Races . Variations of this phrase would later become a frequently used catch - phrase for Daffy Duck and Bugs Bunny in Warner Bros. cartoons . </P>
