If I had to think what the scarecrow would be like in the real world well he would be a mix of a very funny person who could always cheer you up, a bit of a muppet like me but not as bad and a very kind caring person who just about anyone will enjoy hanging out with! so the scarecrow is a perfect example of a fantasy character an absolute mystery that makes no sense accordingly he was born the day before Dorothy came across him so he is one day old ONE! and lastly how does he walk as he is literally stuffed with hay?
sometimes he questions himself about "not having a brain" and always seems to have that on his mind about having a brain when in fact he already has one just must not be very big although whenever the crew gets stuck in a hole (metaphorically) he always tries or does finds away or has a idea so really he is a bit confused and all he needs is to be talked to and understanding is all I think,
