[[caption-width-right:350:Just so you know, that's Pinkie (Harpo) pretending to be a mirror reflection of Firefly (Groucho).]]
Let's not kid ourselves -- this ''is'' the Marx Brothers we're talking about. They could do your taxes and it'd be hilarious. The whole damn movie is one long Crowning Moment Of Funny from five minutes in when Firefly first enters to the fadeout at the end.

* The film gets laughs even before Groucho first appears. The palace is eagerly awaiting the arrival of Rufus T. Firefly, and the chorus sings "Hail, hail Freedonia, land of the brave and free!"... nobody appears. After a [[{{Beat}} pause]], they try again. Nobody. It takes them ''four tries'' before Rufus (who had been sleeping!) finally shows up.
* When Firefly finally shows up, he strolls in from the ''opposite'' side of the room and asks a soldier who they're waiting for, then holds up his cigar like a sword while they sing one last time.
* Groucho's favorite line in the film was, "Remember, you're fighting for this woman's honor, which is probably more than she ever did!"
** On a meta level, Margaret Dumont (who was on the receiving end of the line) had no idea what Groucho meant. When she asked for an explanation, the others immediately jumped at the opportunity to explain it by assaulting her, in good humor of course.
* '''The mirror sequence.''' One of the greatest comedy scenes, if not ''the'' greatest, ever committed to celluloid.
* The trial.
** During Chicolini's trial (which was full of [[ThatWasObjectionable objections, from both sides]]):
--> '''Rufus:''' Look at Chicolini. He sits there alone, an abject figure--
--> '''Chicolini:''' I abject!
* "To War!"
* The encounter with the lemonade vendor. Especially this exchange:
--> '''Vendor:''' I'll teach you to kick me!
--> '''Chicolini:''' You don't have to teach me, I know how!
-->''(to prove his point, he kicks him)''
* Both times Firefly gets the ambassador to call him an upstart.
* The motorcycle and sidecar running gag. The first two times Groucho gets in 'his Excellency's car!', his drive Harpo would go off, leaving the sidecar behind. [[RuleOfThree The third time]], Groucho gets wise. ("Oh no. You can only fool a Firefly twice. This time ''you'' get in the sidecar.") While the motorcycle remains still, Harpo in the sidecar rides off.
-->'''Rufus T. Firefly:''' This is the only way to travel.
* The whole bit where Groucho makes Chico Secretary of War, from start ("You want to be a public nuisance?" "Sure! How much does the job pay?") to end with Harpo showing off his tattoos to Groucho. ("Well, I know one thing. I bet you don't have a picture of my grandfather." Harpo starts to take off his pants.)
* [[https://www.youtube.com/watch?v=FNSNLXNnx-o Chicolini and Pinky's introduction]]. To show Trentino what brilliant spies they are, they walk into his office wearing ridiculous-looking {{Paper Thin Disguise}}s--Pinky even walks in backwards, [[CrazyEnoughToWork wearing a fake beard and a pair of hypno-glasses on the back of his head]]. Trentino just stares at them dumbfounded. Then they throw off their disguises, and Chicolini proudly yells, "We fool you good, eh?"
** Trentino gets a telegram - Pinky intercepts it, looks it over, furiously wads it up and throws it to the floor.
-->'''Chicolini''': "He gets mad 'cause he can't read!"
* The first conversation Rufus has with [[GrandeDame Mrs. Teasdale]]:
-->'''Mrs. Teasdale''': The future of Fredonia rests upon your shoulders. Promise me you'll follow in the footsteps of my husband.
-->'''Rufus''': (''aside to the camera'') [[BreakingTheFourthWall How do you like that? I haven't been on the job five minutes and already she's making advances to me.]] (''to Mrs. Teasdale'') Not that I care, but where is your husband?
-->'''Mrs. Teasdale''': (''sadly'') Why, he's dead.
-->'''Rufus''': I'll bet he's just using that as an excuse.
-->'''Mrs. Teasdale''': I was with him until the very end.
-->'''Rufus''': No wonder he passed away.
-->'''Mrs. Teasdale''': I held him in my arms and kissed him.
-->'''Rufus''': Oh I see, then it was murder! Will you marry me? Did he leave you any money? Answer the second question first.
-->'''Mrs. Teasdale''': He left me his entire fortune!
-->'''Rufus''': (''suddenly friendly'') Is that so? [[RomancingTheWidow Can't you see what I'm trying to tell you, I love you!]]
* Later, Firefly give Mrs. Teasdale one of the most famous {{stealth insult}}s ever put to film.
--> "I can see you now, bending over a hot stove. But I can't see the stove."
* When Freedonia is bombed, Groucho manages to get a giant vase stuck over his head. Harpo's idea of helping is to draw Groucho's face on the outside of the vase.
** FridgeLogic leads to a slightly gross realization when Groucho comments "Last time this happened to me I was crawling under a bed!" Remember, a lot of people of that generation still used [[ToiletHumor chamber pots...]]
** So how do they get the vase off of Groucho's head? [[StuffBlowingUp With]] [[ThereIsNoKillLikeOverkill Dynamite.]]
--> '''Rufus:''' (post-explosion) Any mail for me while I was gone?
* Firefly changing outfits in every single shot during the final battle, starting in his regular black coattails while wearing a confederate hat, then in full confederate garb, then as ''Davy Crockett''.
* When Chico is asked to go out into the war zone:
--> '''Chicolini''': I wouldn't go out there unless I was in one of those big iron things, go up and down like this... What do you call-a those things?\\
'''Rufus''': Tanks.\\
'''Chicolini''': You're welcome!
** Also during the bombing scene, two bombs fly through the window and out the other one across the room. Groucho's solution? Pull down the window shade.
* "JOIN THE ARMY AND SEE THE NAVY"
* During the firefight with the enemy army, Rufus accidentally throws his rifle out of the window.
-->'''Rufus''': There goes my gun (turns to Mrs. Teasdale) Why don't you go out and fetch it like a good girl.
* Rufus' immortal "idiot" line: "Gentlemen, Chicolini here may talk like an idiot and look like an idiot. But don't let that fool you. He really is an idiot."
* Chicolini's status report on trailing Rufus:
--> '''Chicolini''': Monday, we watch-a Firefly's house, but he no come out. He wasn't home. Tuesday, we go to the ball game, but he fool us. He no show up. Wednesday, he go to the ball game, but we fool him! ''We'' no show up. Thursday was a double-header, nobody show up. Friday, it rained all day. There was-a no ball game. So we stayed home and we listened to it on-a the radio.
** Although he comforts Trentino immediately after by telling him that they ''did'' shadow Firefly all day. Which day? ''[[{{Pun}} Shadowday]]!''
* Rufus in a cabinet meeting:
--> '''Rufus''': And now, members of the cabinet, we'll take up old business.\\
'''Cabinet member''': I wish to discuss the tariff.\\
'''Rufus''': Sit down, that's new business. No old business? Very well, then we'll take up new business.\\
'''Cabinet member''': Now about that tariff.\\
'''Rufus''': Too late! That's old business already. Sit down.
* RealLife example: There was a village in UsefulNotes/NewYork called Freedonia who asked the filmmakers to change the name of the town in the film, as it would hurt their image. Groucho wrote back saying, "Change the name of your town, it's hurting our picture".
