There are a lot of well-known mondegreens. ‘Scuse me while I kiss this guy’ and ‘Wrapped up like a douche’ come immediately to mind.
This thread is not for those.
This thread is for lyrics that you, personally, have misheard. Not what other people have misheard; what you have misheard. Granted, you’ve probably misheard the well-known ones. If so, then go ahead and post them – just as long as you, yourself, heard the song and misheard the lyrics. For example, I misheard the line in Games Without Frontiers as ‘She’s so pop-ular!’
The ones I think of, that I, myself, misunderstood, come from childhood. When you’re five years old, you don’t have the database to figure things out.
Lyric: ‘Colonel, he vowed these two soon disappear.’
Heard: ‘Colonel’s a doggie too. Soon disappear.’
Lyric: ‘Times Square!’
Heard: ‘Down Scrown!’ (Makes no sense, but that’s what it sounded like to me.)
Lyric: ‘Good bye, city life!’
Heard: ‘Good bye to your life!’
Lyric: ‘From seven stranded castaways’
Heard: ‘From Chevron-Standard castaways’
