I have some songs where I sing the wrong words because it’s funnier that way.
Mumford and Sons - Sigh No More. The actual lyric is “Man is a giddy thing”, which I sing as “Man is a guinea pig”.
Florence and the Machine - What the Water Gave Me, instead of “pockets full of stones” I sing “pockets full of scones”.
I feel like there are probably some of these where a certain group of people has a modification to the lyrics, like singing “Root, root, root for the [insert your team name here]” in Take Me Out to the Ball Game - but probably more creative than that.
Anything that has been done Weird Al. I cannot hear the original without the parody version rattling around in my head. I usually end up singing the Al version loudly over the original one.
The recent car commercial with Gangster Paradise playing in the background is the ONLY time I have EVER heard the original song. Amish Paradise was what I heard first, and what I will hear forever, no matter what’s actually playing. <3
Also, when J Geils’ Freeze Frame song came out, a Chicago station was big on parody songs, so when I hear it I sing “Faulklands!!” followed by sheep noises.
Same reason I think of firefighters when I hear Starship’s “Jane”. Poor Mayor Byrne; between that and Cabrini Green, she didn’t stand a chance.
“You are like a hurricane./
There’s cum in your eyes”
— Neil Young - Like a Hurricane
“Dye! Dye my hair!/
A darker shade of brown!
It’s too light for me!”
— Metallica - Creeping Death
There’s a parody version of The Doors’ Riders on the Storm, done by Bob Rivers, which is quite brilliant. It’s called ‘Burgers on the Grill’ (youtube) and its lyrics in their entirety are better than the original.
