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.
