In Prince's song "I Would Die for You" I used to think he was singing "Apple Dapple do!"
A childhood belief about misheard lyrics

others believed things like this
- My Mom used to tell me if I swallowed an apple seed I would grow an apple tree inside my stomach!— Marg
- I used to believe that an Adams apple was a piece of apple that was stuck in someone's throat.— Ron Aaron
- When I was a kid, I used to bellieve that when I eat an apple pip an apple tree would grow up in my stomach!Anon
- I thought the big apple was literally a giant apple in New York Anon
- That song that goes:
I'll never let you go...
I thought he was singing:
Another machine gun...
Haha.— Kelle - The buckinghams song "kind of a drag", i always thought they were singing, "Canada Dry"— bobbybobby
