I can’t think of any off the top of my head, but this bit by Peter Kay always has me in tears.

Also, the technical term is ‘Mondegreen’

Edit: I’m also reminded of a Colin Hay one man show I went to years ago where he told a story about a bloke that requested the ‘song about the goats’ at a gig. Turns out it was Overkill - “Goats appear and fade away”. He then went on to tell a long story about a sharehouse he lived in in his youth that decided to get a goat to keep the lawn down. Man that was a good show.

Owner of a lonely horse…

Real lyric: owner of a lonely heart.

I never understood why there’d be a song about a lonely horse.

Hoobastank, the Reason.

Real lyric: “a reason to start over new”.

What i heard as a child: “the reason tostadas are new”

For like a decade+ I thought Umbrella by Rihanna went “under my arms forever”

At one point in Another One Bites the Dust, Freddie says “Bite the dust, yeah” which for years I could not hear as anything but “I’m adopted”. Seemed like a weird way to share that information.

That Land Down Under song. I still have no idea what the women or men do but I can hear the thunder.

I’m here to say that I figured out “stomp on the stoop when you hear the funk loop”. It took me 30 years.

Annie are you walking? Annie are you walking? Are you walking, Annie?

“You know I’d like to keep my cheating strategy”

Actual lyrics: “You know I’d like to keep my cheeks dry today”

Blind Melon, “No Rain”

some daughtry song about Tijuana.

Heard this the other day, the background vocals “who likes tacos”

“Dirty deeds, dunder chiefs!”

I always wondered what a dunder chief is.

“It’s a corned beef sky… alright, is it some other guy…” - The Cars, Bye Bye Love

It wasn’t until my first job at a grocery store during Christmas time that I learned it was “Feliz Navidad” being sung.

Before that, I couldn’t figure out why the cheerful song that only appeared around Christmas time was saying “Police shot my dad”

I used to think the Kiss song went “I wanna rock and roll all night… and part of every day.”
