Analysis of The Overworked Poet

There was a poet, name was stanley creech,
Renowned for poems are love and lore
And sapience and morals that he'd teach,
All from the heart and kept on writing more
Until this happened: He was called upon
To write a poem most exemplary.
His brain he cudgeled but no words could spawn
So randomly he wrote to set this free:
Why is this crowd? What means this stir in Rome?
The Hesperus which breaking waves dashed high
Beneath a chestnut tree, no place like home!
And on and on he elequently wrote
So that from brain to pen these words did float!
