Lyrics:

They call me Mr. Knowitall

I will not compromise.

I will not be told what to do.

I shall not step aside.

They call me Mr. Knowitall

I have no time to waste.

My mouth it spews pure intellect.

And I've such elegant taste.

They call me Mr. Knowitall.

I sup the aged wine.

Oh I could tell such wonderous tales

if I should find the time.

I must be Mr. Knowitall

For ideas they come in bounds.

I am Mr. Knowitall

So spread the word around.

They call me Mr. Knowitall

I am so eloquent.

Perfection is my middle name

And whatever rhymes with eloquent.
