Groucho's cameo....I think this is it....
This occurs @ approximately 36:58 http://postimg.org/image/b5fs3ht53/
shareIs he the African American lady or the Asian American lady? j/k No idea where you see him on that pic.
shareYou're kidding, right? He's the old white guy to the right of the African American lady, below the balloons. Groucho was 81 at the time this was filmed.
shareHuh, I've apparently never seen a picture of him that old. My bad. Yes, when you compare one of his pics from his old age, like this one, they might actually be the same person. Unfortunately, no way to tell for sure, unless they release a bluray of the movie or something.
