Back in the days before the Intarwebs, you couldn't always get the lyrics of popular songs except by actually buying the record album, which frequently had the lyrics printed on the cover or on the record sleeve.
I used to mishear Cyndi Lauper's "Girls Just Wanna Have Fun" line which goes:
When the working day is done
as:
What in the world can they have done
And another song that went:
Oh what a lonely boy
as:
Oh what a lovely war
You got any like that?
