I remember hearing a discussion on the radio once about misunderstood song lyrics, the only example they gave that I can remember was the Steve Miller Band, the line goes "big ol jet airliner" but this person always thought it was "big old Jack had a light on". My husband and I had a long standing joke about that; before Covid he traveled a lot for his job, when he'd return, I'd always ask him about big ol Jack and whether his light was on.
The one that I get wrong every single time, to this day, is Abba's "Take A Chance On Me", when I was young I always thought the chorus was "Olly oxen free" instead of "honey I'm still free". 🤣
My favorite earworm is Sneaky Snake, because it brings back a lot of good memories of my childhood.
