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!
[MARY POPPINS]
He traveled all around the world and everywhere he went
He'd use his word and all would say, "There goes a clever gent!"

[BERT]
When Dukes or Maharajas pass the time of day with me
I say me special word and then they ask me out to tea

[MARY POPPINS & BERT]
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!

[MARY POPPINS, spoken]
You know you can say it backwards which is "dociousaliexpilisticfragicalirupus"... but that's going a bit too far, don't you think?

[BERT, spoken]
Indubitably!

[MARY POPPINS, sung]
So when the cat has got your tongue, there's no need for dismay
Just summon up this word and then you've got a lot to say
But better use it carefully or it could change your life!
[MAN, spoken]
For example...

[MARY POPPINS, spoken]
Yes?

[MAN, spoken]
One night I said it to me girl, and now me girl's my wife!
Oh, and a lovely thing she is, too

[MARY POPPINS & BERT]
She's....
Supercalifragilisticexpialidocious!
Supercalifragilisticexpialidocious!
Supercalifragilisticexpialidocious!
Supercalifragilisticexpialidocious!
