When I was about 10 years old,I used to believe the song by The Commitments, Mustang Sally, was actually Mustard Salad,not a good thing to sing in front your class mates.
A childhood belief about misheard lyrics

others believed things like this
- My mom used to tell me if I ate mustard I would grow mustard.Anon
- the beatles song 'mean mr mustard' says "shes a real go-getter", i was sure it was "shes a real coconut"...— sally
- Croutons are called "Salad cookies"Anon
- I thought that singer/songwriter was spelled this way: sing-a-song-writer...Anon
- in the song "show me heaven" i used to sing "make me breakfast" instead of "leave me breathless"Anon
- I used to believe 'three bean salad' was an extremely small entree because it contained only three beans.— queeneve
