"I'm going back to the farm. I want to help Dorothy. I don't want to be a scarecrow anymore. I want to be a real man."
This line underscores the transformation the Scarecrow undergoes throughout the story. He starts as a simple, unintelligent scarecrow, seeking knowledge and wisdom. After acquiring a brain, he discovers his own potential and purpose, choosing to use his newfound intellect to help others rather than simply reveling in his own intelligence.
