Here, the Stooges, who are salesmen, are chosen to guard the house of Professor Graves by a Japanese spy invasion.
- Bears Are Bad News: Moe comes upon a stuffed taxidermy bear, first being scared by it before realizing it was fake.
- Big Red Devil: Well, not very big (he's only as tall as the boys) but one spy is tricked out like the classic Devil, pitchfork and all.
- Bomb Disposal: The Stooges realize that the bomb was accidentally lit when threatening the Japanese with it. They pass it on to each other right before throwing it at the Japanese, blasting them out of the house.
- Dem Bones: One of the spies is dressed like a skeleton, and manages to terrorize both Larry and Curly.
- Double Take: At one moment the skeleton-suited spy hides under a drop cloth. The panic stricken Curly joins him, only to be shushed by the spy. Curly nods agreement, but a moment later...
- Framing Device: The premise is told through a story by Professor Dunkfeather for a reporter.
- Juggling Loaded Guns: Graves gives one of the boys, which is Curly, the gun. When Graves asks if he knows how to use it, Curly demonstrates its features. When he pulls the trigger, the ricocheting bullet shoots he Stooges' hats off.
- Obviously Evil: The Axis spies are as blatant about their evilness as always, but in a different manner than in other Stooge shorts: instead of walking around in full Nazi regalia and doing the Hitler salute in broad daylight on American soil, these spies are inexplicably dressed in Halloween costumes that telegraph their evil nature — the leader being a Dastardly Whiplash and his two goons being a skeleton and a Big Red Devil.
- Running Gag: An unknown person throwing pies throughout the story.
- Yellow Face: Surprisingly and refreshingly averted for a wartime short; while the scientist explicitly says the spies are Japanese, the spies we actually see have white skin and American accents, implying that they're American fifth columnists.
