Boobs in Arms is the fifty-second short subject starring the Three Stooges.
The short fits neatly into three parts. In the beginning the Stooges are street peddler greeting card salesmen who are approached by a woman (Evelyn Young) with a request to help her make her husband (Richard Fiske) jealous. The Stooges defend themselves against the irate husband with their usual combatives and flee from the husband shouting his threats. In hiding from him, they line up on a queue that took them to a recruitment office by mistake and end up joining the army. The Stooges push drill sergeant Richard Fiske over the limit in Boobs in Arms.
The second part of the short has them meeting their sergeant — the irate husband. The Stooges do the traditional military drill comic routines with gusto and irritate the sergeant even more, including bayonet practice.
The last part of the short has the Stooges going to war against a fictional country and becoming casualties of a laughing gas shell that exploded on them, rather than the enemy, due to their pointing the cannon upward. They and their sergeant are captured by an anonymous enemy in European type uniforms who seem to speak pig latin. Hopped up by the gas, the Stooges gleefully use their violence in a wild free for all fight against their captors — including an accidental sword thrust to the butt of the sergeant and his retaliatory box to the enemy captain that landed his butt to the pointed end of his pickelhaube helmet. The Stooges knock out everyone, including all enemy soldiers and their sergeant. After emerging victorious, several guns suddenly fired at them, with shells whizzing at their area. And they are still laughing.
Finally, the last shot's shell passes between their legs that takes them into the clouds.
