The somewhat thin plot primarily provides a framework for the
running gags of the Marx Brothers to take prominence. The film is, however, notable for its musical production numbers, including cinematic techniques which were soon to become standard, such as overhead shots of dancing girls imitating the patterns of a
kaleidoscope. The musical numbers were not pre-recorded, but were shot live on the soundstage with an off-camera orchestra. The main titles are superimposed over a negative image of the "Monkey-Doodle-Do" number photographed from an angle that does not appear in the body of the film. One of the more famous gag routines in the film involves Chico not knowing what a "
viaduct" is, which Groucho keeps mentioning, prompting Chico to ask, "
Why a duck?". In another sequence, while he is acting as auctioneer for some land of possibly questionable value ("You can have any kind of a home you want to; you can even get
stucco! Oh, how you can get stuck-oh!"), Groucho has hired Chico to act as a shill to inflate the sale prices by making bogus bids. To Groucho's frustration, Chico keeps outbidding everyone, even himself. During the auction, Mrs. Potter announces that her necklace has been stolen and offers a reward of one thousand dollars, whereupon Chico offers two thousand. Unbeknownst to anyone except the thieves and Harpo (who intercepted the map drawn by the villains while hiding under their hotel room bed), the jewelry's hiding place is a hollow tree stump adjacent to where the land auction takes place. Thereupon, Detective Hennessy, who entered the plot earlier, decides that the guilty party is Polly's suitor. He is aided by the real villains, who attempt to frame Bob Adams for the crime. However, Harpo, by producing the necklace, and later the note, is able to prove that Bob Adams is innocent of the charges laid against him. At various points, Harpo and Chico both provide musical solos – Harpo on the harp, and Chico at the piano. Still another sequence has Groucho, Mrs. Potter and Harvey Yates (the necklace thief) make formal speeches. Harpo repeatedly walks off, with a grimace on his face, to the punch bowl. (His staggering implies that the punch has been
spiked with
alcohol.) Another highlight is when the cast, already dressed in traditional Spanish garb for a theme party, erupts into an operatic treatment about Hennessy's lost shirt to music from Bizet's
Carmen (specifically,
Habanera and the
Toreador Song). An earlier scene shows Harpo and Chico abusing a cash register while whistling the
Anvil Chorus from
Il trovatore, a piece also referenced in several other Marx Brothers films. Immediately following the revelation that an injustice has been done to Polly's original suitor, Bob Adams, Mr. Adams himself comes in saying there's a man outside asking for Mr. Hammer: it is tycoon John W. Berryman, who is about to buy Bob's architectural designs for Cocoanut Manor, and asking if the hotel can accommodate 400 guests for the weekend. The Marxes immediately beat a hasty retreat, and Mrs. Potter declares the wedding will take place "exactly as planned, with the exception of a slight change," announcing that Mr. Robert Adams will be the bridegroom. ==Cast==
