When my younger brother was little, he thought the lyrics from Maroon 5's "She will be loved" weren't "I know where you hide, alone in your car", but "I know where you hide, Bologna your car". XD
A childhood belief about misheard lyrics

others believed things like this
- I used to believe that hydrangeas were so called because rangers hide in them.— Ross
- I used to believe that the inside of my body looked like bologna.— Stephenie
- I used to believe that they got the lunchmeat bologna from cutting off dead people's butts.— angie
- My mum told my older brother that dogs weren't allowed in London.— Fiz
- I always thought that Little Richard was Cliff Richards younger brother— adam
- When I was younger, I thought my brother kept eating my dirty socks, and that's why his feet smelled.— Kail
