Story about this misheard lyric by: Miranda Turner

Back when I was a middle school student, I was at the home of my older sister who was already married. My brother-in-law was listening to some of his favorite oldies discs, and that's how I heard this song for the first time. It made a considerable impression on me, and a while later I was singing part of it, with the above misheard lyrics. My brother-in-law chuckled and said, 'What's that you said?' I told him and he broke out laughing uncontrollably. Later when I halfway convinced him that I wasn't singing it funny on purpose but really thought I'd heard the words that way, he told me that it was interesting, and that 'Lucy's Butterfly' might be an actual kind of butterfly. He got out a butterfly book and showed how a lot of real kinds of butterflies have girls' names. But he couldn't find a Lucy's Butterfly after all. He decided he must have gotten the idea by confusion from Lucy's Warbler, which he knows to be a real kind of bird.
