This morning I watched Oklahoma! for the first time. I think I may have read somewhere that this is the source of the line "Never mind the furthermore, the plea is self-defense" in "Zilch" (and also "No Time"), but now that I've actually seen the movie, I know the context from which the line is taken.
Near the end of the movie there's an improvised trial (something of a formality that the characters want to rush through), and as one character explains his actions ("And furthermore..."), he's interrupted by the judge, who says, "Never mind the 'furthermore,' the plea is self-defense." Because I hadn't seen the movie and didn't know the context, I didn't know that the "furthermore" in this quote is itself a quote.
