Take their tails
Listened to James Gordon’s song “Small Town Prairie Gigs” this afternoon. One of the verses is about meeting townsfolk; I was surprised at the line that went like this:
Sometimes we'd take their tails back home with us…
…but then I realized that of course he’d actually sung tales.
I guess it still counts as a Mondegreen if you hear the sound of the word right but you interpret it as a homonym.
