Shemp Howard is relatively restrained in this Columbia short. By and large Big Boy is actually the lead comic and Shemp supports him. Frankly, that's the way I prefer Shemp. He's fine in small doses, but let him loose with his tics and noises and bluster and I don't like him.
Here, with Williams to take the brunt of the Jules White gags -- the standard one here is when they eat a feather oven mitt -- it's actually about two young men, competing for a girl. One is heading off to college and a bunch of youngsters come over for a party, with almost a score of them in one shot.
It's a pretty good comedy, in no small part because in 1940, the budget of a Columbia short would still support a few niceties like a cast. After the War, inflation would eat into those budgets. For the moment, though, it was still enough. Enjoy it while it lasts.
