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!

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 achin' 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!

He traveled all around the world
And everywhere he went
He'd use his word and all would say
"There goes a clever gent"

When Dukes and maharajas
Pass the time of day with me
I say me special word and then
They ask me out to tea

Supercalifragilisticexpialidocious!
Even though the sound of it
Is something quite atrocious
If you say it loud enough
You'll always sound precocious
Supercalifragilisticexpialidocious!

Spoken:
No, you can say it backwards
Which is dociousaliexpilisticfragicalirupus
But that's going a bit too far, don't you think?

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

For example
Yes
One night I said it to me girl
And now me girl's my wife
Oh, and a lovely thing she's too

She's...
Supercalifragilisticexpialidocious
