Music and Lyrics by Robert B. Sherman 

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

Because I was afraid to speak
When I was just a lad My father gave me nose a tweak And told me I was bad
But then one day I learned a word That saved me aching nose
The biggest word I 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
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 may change your life
One night I said it to me girl
And now me girl's my wife!

She's supercalifragilisticexpialidocious!
Supercalifragilisticexpialidocious!
Supercalifragilisticexpialidocious!
Supercalifragilisticexpialidocious!

From the Walt Disney Productions movie musical "Mary Poppins" (1964). Sung by Julie Andrews and Dick Van Dyke as "Mary" and "Bert."
