Dollar Bill:

I'm cost efficient
The root of all evil,
I'm one of a kind
I don't have no equal.

I'm green in color
Known the World over,
But I'm hard to come by
Like a four leaf clover.

I'm made of special paper
With a strong money odor,
But it never ever matters
To the nose of my owner.

I make the World spin
For I do get things done,
Yes I'm all about business
But I do have some fun.

I'm always on the run
Cause I do get around,
In every single Country
My green back is found.

I've been over this Globe
I've done just about all,
And I'm a really big hit
At all shopping malls.

Put me in your wallet
And please keep me safe,
Or I'll disappear like crazy
Right in front of your face.

I don't hang around long
For I've got things to do,
And if you try to save me
Then I'm no good to you.
