trench coat, in the I Love Lucy episode "Lucy and Harpo Marx". Other scenes and jokes 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): 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! Another repeated gag involved Harpo, who drives a motorcycle with a sidecar, as a chauffeur, to transport Groucho.

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".

Variations of this phrase later became a frequently used catch-phrase for Daffy Duck and Bugs Bunny in Warner Bros. cartoons. In another scene, the film pokes fun at the
