This being the second half of a Marx Brothers double feature. Not very good at all, unfortunately. No musical numbers whatsoever. No Margaret Dumont. Unfunny premise. If you need to say you've watched all the Marx Brothers movies, go ahead; otherwise, avoid.
Lucille Ball and Ann Miller appear, although they don't do anything notable.
Intriguing theory: although Zeppo was not funny himself, Zeppo's presence was a necessity for a first-rate Marx Brothers movie. Discuss amongst yourselves! Although I have no idea how you would go about doing that.
