That's about the point that I realized that it was in another language. A language that, not only could I not understand, I couldn't even *identify*. That cuts out the Romance languages and German. Beyond that? My money's on Japanese, but that's kinda my default for those which I cannot identify. They kept throwing in English, too. It was strange. Basically, what I heard was "[incomprehensible] trick or treat [incomprehensible] upside-down." And at the end, I heard what I imagine was the line "Last year's rent/this year's rent/next year's rent" in whatever language, followed by a line of "Rent rent rent rent rent" in English.
I am confused. Doesn't take much, I know, but still.
