IMDB

Captain Spaulding (Groucho) is invited as the guest of honor to a society function. A painting is stolen by Harpo and Chico. Groucho tries to investigate, but that doesn't turn out well, because he's Groucho. Insanity ensues. "Insanity ensues" could be the entire plot description of nearly any Marx Brothers film.
The Marx Brothers' second film still isn't quite as frantic as Monkey Business or Duck Soup, but it's still an amazing comedic masterpiece. Nearly every Marx Brothers movie is worth watching, especially those from their early career. Watch it, y'all.

10/10
