Up until recently, I had never heard of Benny Rubin. However, I was able to download several of his RKO comedy shorts for free at archive.org--and wasn't all that impressed with his very ethnic humor. I was surprised to see only a week later that Turner Classic Movies showed one of his films--a very early color comedy from MGM. Because of my other experiences with Rubin, I set my expectations very low! Benny shows up at a sanitarium where he meets with the doctor (Vernon Dent). Lots of typical Rubin verbal humor ensues. Then, one of the doctor's assistants shows Rubin around the place. Inexplicably, the place has a radio program (????) and everyone around the place WAY overplays their crazy routines. In the middle of this goofiness, a black man does a very strange dance routines that has NOTHING to do with the film nor does the subsequent musical number--both of which are, apparently, part of the radio program.
Like the other Rubin films I saw, I just didn't like this one. Rubin's verbal schtick just didn't appeal to me as it didn't seem funny. The only things that made me laugh all happened in the final scene (which was pretty cute). Not recommended unless you adore Borscht-Belt comedy.
By the way, the color appears to be a two-color process where an orange-red strip and a green-blue strip are overlapped on a black & white strip. Cinecolor and Two-Strip Technicolor used this process and the film used the primitive Technicolor print.
