Very likely their best film. This is pure surrealism from start to finish, with some of their best-executed routines, and a welcome absence of (serious) musical numbers. Whether it has Harpo answering the phone, Groucho explaining his tax policy or Chico giving a detailed report of his weekly surveillance tactics ("On Wednesday we fool him: We no show up"), this is the epitome of the Marx Brothers movies. And here's one of the funniest lines that nobody else has mentioned: "Ok, I give up. How about your glass of water?" (well, it's only funny in context). (***)
