[PW] question: legal expression, proverb, etc. "gets the grease from the goose"

[David Rash]

A faculty member is looking for the origin of a phrase which shows up in
several legal cases: "gets the grease from the goose".  The context
seems to indicate self generation or self incrimination but I could be
wrong about this.  We have tried standard quote, proverb, slang
dictionaries, Biblical concordance, concordance to Shakespeare, legal
dictionaries, Dictionary of American Regional English, Idioms and
Phrases Index, OED, Oxford Online databases, Historic NYT, etc. all to
no avail. Please  Help!
