This is Part of an Army Personal Hygiene Training Film, made in 1950. This is housed at archives.gov.
A
stinky Hillbilly named Homer doesn't bathe or have any other
recognizable hygiene habits. His barracks mates are harsh at first with
him to clean up his act, but soon try making up folk songs like "What
are you gonna do with a dirty soldier?" another about brushing his
teeth and more.
You will laugh out loud at the its-so-stupid
its-funny lines and songs the soldiers sing. I feel sorry for an
American GI who had to endure this film, but I'll bet they got a good
laugh!
