I saw this short on TCM.
It starts with stock footage shots of regular people punching time clocks and working in normal jobs while narrator Pete Smith reminds us that most people have normal, routine, unexciting jobs in offices, shops, and factories with scheduled hours. He then states that some people have very unusual ways of earning their living, and that he has "combed" the land and years for examples. This is a very interesting premise... unfortunately...
What Pete really meant to say was that he really only combed MGM's stock footage of circuses, carnivals and state fairs for the examples. We are shown footage of gymnastic acrobats, horseback acrobats, high wire artists, pole swayers, flying trapeze artists, a horse diver, and a diving stuntman. In fact, the only example that doesn't fall in the narrow category of aerial or gymnastic acrobat is the married couple who perform trick shots with horseshoes. While it's true that most people have routine jobs, the world has a very wide variety of people who make a living in very unusual and very different ways, but this short only shows us examples from one narrow group.
If you just want to see aerial and gymnastic acrobats, then you'll enjoy this short. However, in terms of fulfilling it's interesting premise, this short is very lazy and uncreative and inadequate, and it's most likely 100% stock footage shots. And none of Pete Smith's attempts at humor in this one are memorable.
I wonder if some poor kid saw this short in the 50's and said "Gee... my only two options in life are working a boring 9 to 5 job... or joining the circus".
