Just who or what is Stoodwall?

He is traces left of million dollar cheques expired; baseball hats lost and littered in back alleys in big cities. Stoodwall is drinking a cesar in the morning with his marajuana cigarette. He's a big deal to some few. He is the skinny guy batting his long lashes in wide eyed angry disbelief. You called him Robin Williams and he’s not taking too kindly to it. Stoodwall is your paddle boat left man, your rooftop companion, your doctor . Doctor of what?, you ask. Doctor with a half a credit in astronomy, he smugly replies.
