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

You should have known that one. =)
