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

So, I was afraid to speak when I was just a lad,
My father gave my nose a tweak and told me I was bad,
But then one day I learned a word that saved my aching nose,
The biggest word you've ever heard and this is how it goes

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

You should have known that one =)
