Who marched in to my classroom today...

Hey little rude girl
Don't know why you got under my skin
Maybe because I closed the door on your ass
And you still busted right on in
Be happy that I need my job
And I frequently meditate
Cause you have no idea
The four letter words you were about to face
Little girl you don't know me
Don't know what makes me tick
Bust in my room like that again
And you'll find out real quick!
