Lyrics:

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
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!
