Charley is having a weird first day teaching at a boy's school. He gets into an argument with an iceman, rescues Florence Roberts' canary and is roped into teaching a kindergarten class -- and, of course, falls in love with co-star Betty Mack.
This one is mostly about the co-stars. Billy Gilbert shows up as the rather fey principal of the school and Charley's class is composed of members of Our Gang. Charley had a long connection to Our Gang. He had been the supervising producer of the series in its first year and had appeared in a couple of their shorts in the middle of the previous decade.
This one is structured a lot more erratically than most of Chase's shorts in this period, but he does get to sing a duet with Betty Mack to close out the movie. As with almost all of his shorts, this one is a delight.
