As a child, I thought the song "The farmer in the dell" was instead "The farmer AND the dell". I knew what a farmer was from the time I first remember hearing it. But I spent a lot of time wondering what kind of occupation one would have if one were a "dell", before I finally learned the real lyrics and what a dell actually is.
