American Spoken Here

An off-screen narrator tells us that English is two languages, standard and slang. We watch several quick conversations spoken entirely in slang. Then, in reenactments of scenes from the past, actors illustrate the origins of some common expressions while the narrator explains them: minding one's P's and Q's, kicking the bucket, pin money, doing a Brodie, and, in a lengthy concluding segment, the derivation of "fink."
