Shinola was actually, a brand of shoe polish
at one time, manufactured in the USA,

the marketing, was aimed a dim wits

that old 'ola' suffix
ended up, on a lot of things
cola, crayola, granola, etc.,

the phrase likely came out of the war, the second one
where it orginiated.

Other "does NOT know" phrases,
were popular in the war,

"he does NOT know enough to pee down wind"

"he does NOT know his ass from a hole in the ground"

"he does NOT know whether to scratch his balls, or wind his ass"

or, was that one

"he does NOT know whether to scratch is watch, or wind his ass"

was it NOT Sir Henry Wood who eXpressed
a similar comment/and, opinion when he would say:

"he does NOT know his brass from his wood wind".

lots of good sayings, for sure

No. Just pointing out how perspective works.

You may have the last word.
