Supercalifragilisticexpialidocious Dick Van Dyke & Julie Andrews

[MARY POPPINS]
It's... supercalifragilisticexpialidocious
Even though the sound of it is something quite atrocious
If you say it loud enough, you'll always sound precocious:
Supercalifragilisticexpialidocious

Um diddle diddle diddle, um diddle ay
Um diddle diddle diddle, um diddle ay
Um diddle diddle diddle, um diddle ay
Um diddle diddle diddle, um diddle ay

[BERT]
Because I was afraid to speak when I was just a lad
Me father gave me nose a tweak and told me I was bad
But then, one day, I learned a word that saved me achin' nose

[MARY POPPINS & BERT]
The biggest word you ever heard, and this is how it goes:

Oh, supercalifragilisticexpialidocious
Even though the sound of it is something quite atrocious
If you say it loud enough, you'll always sound precocious
Supercalifragilisticexpialidocious

Um diddle diddle diddle, um diddle ay
Um diddle diddle diddle, um diddle ay
Um diddle diddle diddle, um diddle ay
Um diddle diddle diddle, um diddle ay
