Editing Duck Soup (1933 film) (section)

===Mirror scene===
In the "mirror scene", Pinky, dressed as Firefly, pretends to be Firefly's reflection in a missing mirror, matching his every move—including absurd ones that begin out of sight—to near perfection. At one point, the two men swap positions, introducing the question of which is the reflection. Eventually, Chicolini, also disguised as Firefly, enters the frame and collides with both of them.

Although its appearance in ''Duck Soup'' is the best known instance, the concept of the mirror scene did not originate in this film. [[Harold Lloyd]] used essentially the same routine in his short ''[[The Marathon (film)|The Marathon]]'' (1919). [[Max Linder]] included it in ''[[Seven Years Bad Luck]]'' (1921), where a man's servants have accidentally broken a mirror and attempt to hide the fact by imitating his actions in the mirror's frame.<ref name="Steffen">James Steffen [https://www.tcm.com/tcmdb/title/500600/seven-years-bad-luck "Seven Years Bad Luck" (TCM article)]</ref> [[Charlie Chaplin]] used a similar joke in ''[[The Floorwalker]]'' (1916),<ref name="filmsite"/> though it did not involve a mirror.

This scene has been imitated many times; for instance, in the [[Bugs Bunny]] cartoon ''[[Hare Tonic]]'',<ref name="filmsite"/> the [[Mickey Mouse]] cartoon ''[[Lonesome Ghosts]]'', ''[[The Square Peg]]'' (1959), ''[[The Pink Panther (1963 film)|The Pink Panther]]'' (1963), the [[Tom and Jerry]] cartoon ''[[Cat and Dupli-cat]]'' (1967), ''[[Big Business (1988 film)|Big Business]]'' (1988), the ''[[The X-Files|X-Files]]'' episode [[Dreamland (The X-Files)|"Dreamland"]] (1998), ''[[Garfield: A Tail of Two Kitties]]'' (2006) and the ''[[Family Guy]]'' episode "[[Road to Germany]]". Harpo himself did a reprise of this scene, dressed in his usual costume, with [[Lucille Ball]] also donning the fright wig and trench coat, in the ''[[I Love Lucy]]'' episode "Lucy and Harpo Marx".<ref>[https://www.imdb.com/title/tt0609287/ ''I Love Lucy'': "Lucy and Harpo Marx"] at the Internet Movie Database.</ref>
