See what I mean Shiela? You've got the logical form, the semantics, and all that, but you don't know shit from Shinola, and with your stupid heuristic learner you can't learn it unless somebody with authority tells you..
know shit from shinola
Etymologie
() A colloquialism which dates back to the early 1940s in the United States. Shinola is a a once-popular, now-defunct shoe polish brand, which had a color and texture not unlike feces; the joke in the idiom being that only a stupid person could confuse the two upon more than a passing glance.
