Mondegreens! I love mondegreens.
Speaking of classic Rolling Stones songs, for years I thought the first line of the chorus of "Ruby Tuesday" was "Goodbye, Groovy Tuesday."
From Steppenwolf's “Born to be Wild”:
The line “Fire all of your guns at once and explode into space,” I used to think was “Buy all of the guns and watch them explode into space.”
And in the song "Tonight" from West Side Story -- the line "Today the world was just an address" I always used to hear as "Today the world was just a mattress."
Me too!
Nice ones!
Some mishearings I've heard:
Stand Back -- Stevie Nicks
What I thought I heard -- 'Don't turn away my friend, like a weirdo I can't bend...'
The real lyric -- 'Do not turn away my friend Like a willow I can bend'
Old Time Rock & Roll -- Bob Seger
What I thought:
Just take those old records on yourself (


)
What the lyrics really were:
Just take those old records off the shelf
I was singing this song awhile ago and got the lyrics messed up by mistake, due to being somewhat tired.
I finally understand the lyrics from Billy Joel's song, We Didn't Start The Fire. For years I misunderstood two parts from it...
What I thought the lyric was: Little Rock, Pasternak, Mickey Mantle, Kerouac
Sputnik, Chou En-Lai, Bridge On The River Kwai
Lebanon, Charles de Gaulle, California baseball
Starkweather Homicide,
Children of The Little Mind...
* Keep this in mind, I was a little kid when I first mis heard this, I wasn't being disrepectful to people in any way. I only finally understood the lyrics this year. Thank you Mr. Joel and your singing

.
What it really was: Little Rock, Pasternak, Mickey Mantle, Kerouac
Sputnik, Chou En-Lai, Bridge On The River Kwai

Starkweather Homicide,
Children of Thalidomide...
The other misunderstood one: Buddy Holly, Ben-Hur, Space Monkey, Mafia
Hula Hoops, Castro, Edsel is a no-go
U2,
Cinnamon Ring, payola and Kennedy
Chubby Checker, Psycho, Belgians in the Congo
* Ok, this one makes no sense at all

, but that's what I hear EVERY time he sings that part of the song.
