Is That...?

"Is that a booger on your finger?"
A classmate once said to me
So I looked at him and told him
That he would soon see.

I took my boogered finger
Green snot smeared and all
And chased him out of the classroom
Until he hid inside a stall

When I walked back in the classroom
Everybody stared at me
For the booger on my finger
Had now transferred to my knee

And at this very moment
A thought flew through my mind
And sooner I grew confident
That I'm a special kind.
