I thought that "toony" was a slang term for a part of your body of which you had two, as in the song "Ballin' the Jack" (First you put your toonies close up tight). (OUCH!)
I used to believe part of the lyrics to Fall Out Boy's "Centuries" went:
"You look so pretty, but your gun's so soon."
When, really, it's
"You look so pretty, but YOU'RE GONE so soon."
I thought the lyrics to "Single Ladies" were "If you liked it, then you should've put your name on it."
I used to believe that the lyrics to Mull of Kintyre were bollocking time
Up until I was like 7 or 8, I thought the lyrics to the song "Last Christmas" were, "Last Christmas, I gave you my harp..."
I thought Total Eclipse of the Heart went "nothing I can see, total eclipse of the sun".
I thought the "physically fit" lines in the song "I Like to Move It" were "fizzy coloured feet".
I used to think that the lyric "boiled or stewed, whole or chewed" in Cookie Monster's healthy food song was "almond stew, polo chew".
I always thought the lyrics in I'm Blue were "I could beat up a guy"
When I was 5-7 I thought "let the bodies hit the floor" was "let the parties at the flow" I knew about that song because I watched youtube back then (this was like 2008-2010) so there was many videos with that song in the background. I didn't know much english but knew a few words. After I found out the name of the band was "drowning pool" I thought they lived in an inflatable empty swimming pool that was stranded at the middle of the ocean.
I used to believe the line, "take it back now y'all", in the Cha Cha Slide was "take it back daddy y'all".
Up until five minutes ago, I thought the lyric in Maybe Tomorrow by the Jackson 5 was "I only know my head when it's here on Earth, this time you'll look into my eye" when it turns out it's really "I only know my heaven is here on Earth, each time you look into my eyes". It's strange because my version still made sense to me.
i thought "two pence a bag" from feed the birds from mary poppins was "toppins of ag"
The song called heart of glass mixed me up as a kid. I heard "Heart and ass".
When I was a kid in the song "Boom Boom Pow", I thought the lyrics "Gotta get that" was "Got a kitty cat".
When I first heard the song "Feliz Navidad", I had no idea that it's a Spanish phrase, so I thought it was actually something like "At least knock me down"
I used to believe that swing low sweet chariot was talking about some guy named Jerry-O. I may have read the word chariot but never heard it. Also, I thought "Jordan" referred to my mother's maiden name, not knowing of the river.
I thought the lyrics to Changes by David Bowie specifically the second verse "I watch the ripples change their size but never leave the stream of warm impermanence" as "I watch the nipples change their size but never leave the stream, I want another sandwich"
I thought until I was 11 years old that it was "Little Miss Muppet, Sat on a tub-pit, eating her Kurds and lye"
In the Beatles "Help", they sing "and I do appreciate you being 'round", "'round"of course being abbreviated for "around". However, I thought they were singing about appreciating someone literally being round. I thought it was nice they were so appreciative of fat circle-shaped people.
