I'm sure my mother was half horrified, half amused when she came upon her 8 year old daughter (me) dancing around and singing "Bootylicious" at the top of my lungs. With one minor change in lyrics:
"I don't think you're ready for the spaghetti, I don't think your ready for the spaghetti...."

You know that old song 'How Bizarre' by OMC? Here's the actual lyrics to a part of the song:
"Cruising down the freeway
In the hot, hot sun"

When I was little I was convinced they said this instead, and always sang it this way:
"Cruising down the freeway
In my hot croissant"

When we used to sing the hymn "O happy day" in Sunday school I used to think that the line "he taught me how to watch and pray" was actually "he taught me how to wash and play" - as young child seemed to make sense....

When my dad was little he thought "I shot the Sherriff" was "I'm shockin' Sherry". To this day (I'm grown up now) if I am with him when that song comes on I will start singing "I'm shockin' Sherry" and we both get a good laugh

In the song "Makes Me Wonder" by Maroon 5, there's a line that goes, "Wake up, bloodshot eyes, struggle to memorize". But when I heard it the first couple of times, I thought it was, "Wake up, brush my eyes". I envisioned Adam Levine grabbing a toothbrush and vigorously getting rid of eye plaque.

When I was little I belived a song called, "That's why they call it the Blues," was, "That's why they call it Baboons." I mean come on the lyrics are, "Laughing like children (They make laughing like noises)
Living like lovers (I thought they were cute and loving)
Rolling like thunder under the covers (Like them banging on thier chests)"

I thought the lyrics to "Camptown racer" were:

"Countdown ladies sing this song! Tuna! Tuna!"

Later, I figured out that they weren't saying Tuna, but even after that, I thought it was "Countdown ladies"

I used to think that the song "Evil Woman" was "Medieval Woman".

i used to think that The Who song went "let milo open the door..." not my love .. i always wondered who milo was (another pinball wizard???)

My six-year-old brother sings the chorus to McLean's American Pie like this:

"Hi hi this American guy
Drove my buddy to the beddy
But the beddy was dry
Then good old toys
With wiskers and rye
Singing this will be the day I die."

I used to think that there was a line in the Box Tops song "Cry Like A Baby" that was "When I think about the good lucky caveman, I cry like a baby." (The line actually was "When I think about the good love you gave me, I cry like a baby.")

It made perfect sense in my head--the singer envied cavemen since they got to live in a world unsullied by pollution. I made up my mind that the song was an environmental message.

my neice (who is 9 at the present moment) used to love Britney Spears. Me and her mom used to ask her to sing her Fav Britney song and she always chose "OOPS I did it again". But instead of saying
"OOPs I did it again...I played with your heart...got LOST in the game..she said...

"OOPS! I doo dooed again...I played with your heart...Got LUCKED in the game

lmao we never bothered to correct her...it was way too funny!

My parents really liked Tom Petty and the Heartbreakers. So imagine my mom's amusement when, in the car at age 2, I asked her to put on "Running Down The Drain". It was really "Running Down a Dream", but... I liked mine better, and I still do. =P

The Beatles song "Ticket to Ride" always came out "She's got a tick in her eye."

Kurt

I thought in the song Zombie by The Cranberries she was not saying "In your head, in your head, zombie, zombie: but rather "In your head, in your head, ze army, ze army" (i.e the army said with a German accent, and for some reason it didn't occur to me that she didn't have a German accent any other time she sang..)

Demond

I used to think that in the Bruce Springsteen song that he was saying "Is that you, baby, or just a bridge in disguise?", rather than "brilliant disguise". I also that that when Madonna said "Let the choir sing" in Like a Prayer that she was saying "Level crossing". Much better, I think.

A huge baseball and Beach Boys fan as a young kid (and still am), I used to believe "Catch A Wave" meant going to the beach, running to the water's edge with your baseball mitt and trying to catch the water rushing towards you.

I used to believe that in U2's 'With or Without You', he was singing "whistle without you" with a strong lisp!

Whithle without you~

When I first heard the song 'Vogue' by Madonna, I thought they were singing 'Bo' and it was a song about a shy boy named Bo who was afraid to dance.

I always thought that the chorus to the Cutting Crew song "(I just) Died in your arms" went "Ha-rah, I just died in your arms tonight, it must have been some kind of cheese." Makes sense, there are some nasty cheeses out there.
