In the song "Dream a little dream of me", there's a line that goes, "birds singing in the sycamore trees, dream a little dream of me"... My roommate and I were listening to this song last night and I asked her if she knew what a sycamore tree was, and she told me that I misheard the lyrics and that line actually went: "birds singing in the sake of more trees"....
Well, I was quite convinced by her that it was me who misheard the lyrics, ha!
