It was in fact from the German. I like the suggestion that the CI should feel like "nothing at all" (rather than the painful slow trial-and-error process of setting up most CIs, which makes you very much aware of them).

I also happen to live very near where Marlene Dietrich lived, who has a famous song in which "und sonst gar nichts/nix" is the refrain ("and nothing else") [0]. When garnix becomes a noun of its own, as here, it reads instead as "and otherwise, garnix", which I find mildly funny.
