Poet and didn't know it

Sonny Boy had an assignment yesterday in Social Studies. Students were to write a poem about slavery. (Please bear in mind that he has always had close friends of a variety of races and is really concerned with racial justice, but his need for humor took precedence yesterday.) The poem went as follows -

I am a slave sitting under a tree
I wish I was free
Oh, look there's a bird!
He just dropped a turd!

He said the class (very diverse group of students) all thought his was the best. 13 year old taste...
