I always thought instead of saying "Im a material girl" Madonna was saying "Im a cheerio girl".
A childhood belief about misheard lyrics

others believed things like this
- When I was younger, I saw Madonna's video for "Material Girl". I thought she was singing "I'm a Cheerio Girl"!— Greg
- That Madonna sang "I'm a cheerio girl" instead of material girl— HN
- I used to believe that the words to Michael Jacksons "Liberian Girl" were "librarian girl".— Paul
- I use to believe that a "Prima Donna" was "Pre-Madonna"---someone before Madonna's time.
