Knutzy Knights (1954)

The stooges make a whole batch of homemade beer, but get tossed in jail when Curly sells some to a cop. Their minor indiscretion turns into a forty year sentence when a keg of beer Curly has hidden under his coat explodes while the boys are being photographed. In prison the stooges get into more trouble with the warden and wind on the rockpile when they try to escape. Released as old men with long gray beards, the first thing Curly wants is a bottle of beer.

The stooges are dressed as Japanese soldiers for their job as magazine models. On their lunch break they go into a restaurant with their Japanese uniforms on causing the proprietor to mistake them for the real thing, and a chase ensues. The boys fall through a trap door, and into a nest of Nazi spies where they are mistaken for "Naki", "Saki" and "Waki", three Japanese saboteurs. The stooges try to act the part, including demonstrating acrobatics and jiu-jitsu to their hosts. When the real "Naki", "Saki" and "Waki" show up, the boys are exposed and impostors, but after a wild fight manage to capture all the Axis spies.

The stooges are discharged from the army and go to see their fiancée, but find they have been dispossessed and the wedding is off until they find a home. The boys have trouble finding a vacant apartment so they set up housekeeping in a vacant lot. Their housing problems seem to be solved until a farmer destroys their new home with a tractor. The stooges then build a house of their own, but the girls aren't impressed with the one room mansion and walk out on them.

The stooges are pharmacists who invent a fountain of youth formula that can turn old people young. They turn an old lady into a beautiful young woman, but when her husband takes the formula it turns him into a gorilla.

The stooges are private detectives looking for a missing millionaire. They wander around the millionaire's spooky mansion confronting various crooks and a dangerous dame. The stooges vanquish the crooks (Shemp uses his "trusty shovel") and find the missing man.
