When Kate Bush first had a hit with the song 'Wuthering Heights' I and my sister then aged 8 & 10 actually thought the chorus went like this,
'Wee wee, its me, I'm a tree, I'm a wombat, so cold at the end of your winter'
And then we heard 'gypsies, tramps & thieves' by Cher, but thought she was singing 'Gipsy Chimpanzees'
A childhood belief about misheard lyrics

others believed things like this
- When I first heard the song "Constant Craving" by KD Lang, I thought she was singing "God save gravy."Anon
- i thought president Bush was an actuall bush.— oops
- When I first heard Matt Monro's song "Born Free," I thought he was singing "Porn Free."Anon
- I swear I heard a Disney Channel/Radio Disney song where the chorus was a repeated “Damn it”— SpengBab
- I used to falsely believe that planting a fruit pip in the garden would actually grow a tree or bush.— Natasha
- That song that goes:
I'll never let you go...
I thought he was singing:
Another machine gun...
Haha.— Kelle
