A mondegreen is a word or phrase derived from misunderstood song lyrics. It came from a song with the words, “…and laid him on the green,” which was interpreted to be “…and Lady Mondegreen.” I remember a joke I read when I was a kid describing a kid in Sunday School drawing a nativity scene with a roly-poly fellow standing off to the side. When the teacher inquired about him, the kid said it was “round John Virgin.”
So okay. I hardly know any Beatles lyrics, so I can’t appreciate the humor in this Soup to Nutz strip, but you probably do, so you probably will.
If you’re of a didactic bent, feel to translate these into the real lyrics for me in the comments.
