I saw this on a CD that presented it as a Laurel and Hardy short. Early on I recognized Buster Keaton and thought "That's strange, I never heard of Keaton working in a Laurel and Hardy short." Of course, it turned out not to be a Laurel and Hardy film at all. It's one big in-joke with seemingly every Hollywood star of 1931 making a cameo appearance. I recognized many but was surprised, watching the closing credits, how many I had missed. In that light, it's great viewing for fans of that era. Otherwise you can easily take it or leave it.
