What song originally had the words "scrambled eggs" as the main theme while it was being written because it had the same number of syllables?

The melody for the song "Yesterday" was written first. Having no lyrics yet and in an attempt to remember the tune, Paul McCartney sang the words "scrambled eggs, baby I love scrambled eggs" repeatedly.
