When my younger sister was about 5 she misheard "Sad Sweet Dreamer" - she thought they were singing "sexy people, it's just one of those things you put down to experience". Well maybe it is, but I'm sure that's not what they're singing!
A childhood belief about misheard lyrics

others believed things like this
- I always thought Hot Chocolate were singing 'You Sexy PIG' instead of 'You sexy Thing.— Bilz
- When I was younger, I saw Madonna's video for "Material Girl". I thought she was singing "I'm a Cheerio Girl"!— Greg
- I used to think Right Said Fred sung 'I'm too sexy for my lamb' instead of 'I'm too sexy for Milan'.— Nineties music was great
- I used to think tiny little people were inside my mothers radio singing to me.Anon
- That song that goes:
I'll never let you go...
I thought he was singing:
Another machine gun...
