The world is full of very good examples:
'Oh a Tree in Motion, dancing close to me...'
'A year has passed since I broke my nose...'
or that old Beatles classic:
'The girl with colitis goes by...'
The phrase itself was apparently coined by Sylvia Wright and was itself based on a mondegreen. In the poem, 'The Bonnie Earl O'Murray', Sylvia heard a line refer to '... and Lady Mondegreen' which was in fact, '... and laid him on the green.' It's quite a fine example and a great way to give a name to something. (Thanks to Wikipedia for some information on that last bit.)
Anyway, I have my own favorite Mondegreen. I guess I love it so much becuase nobody told me about it, it was my own mistake and I made it proudly all by myself.
My favorite one happens in the song 'Golden Brown' by The Stranglers.
Ever since I have heard this song I have believed the lyric to be:
"Golden brown, texture like sun lays me down With my Mancherons."
(If possible have a little listen to the song before reading the rest, I'm sure you'll hear it too)
I always sang along happily (as you do) until, one day I started to wonder what the hell a 'Mancheron' was.
I looked it up and found out that it was, "a very short sleeve not extending below armpit level"
Okayyyyy... so this guy lay down in his short sleeves... 'relatively happy with that.
But then, listening to the song one day, the truth suddenly came to me in a blinding flash of light.
He wasn't singing "with my Mancherons" at all. He was singing "with my mind she runs".
This was a real epiphany for me.
It was similar to the time (quite recently) when I worked out that the expression 'Seconds Out', as used when a round of boxing is about to commence, does not mean that there are only seconds left before the boxing starts but rather means that the boxers assistants or 'seconds' should remove themselves from the ring.
The key to loving these revelations (for me anyway) is that you can't be told them, you have to figure them out for yourself - no matter how far behind the rest of the world you are.
So I love my 'Mondegreen' mistake because:
a) If you think it is 'Mancherons', it really sounds like 'Mancherons' but as soon as you know the truth, you will never ever hear 'Mancherons' again and
b) Lots of people have apparently made the same mistake as I did and they continue to do so to this very day.
c) I did it all by myself and that makes me feel a bit proud.
