why do you think the naeeator began his introduction of himself with an explanation of his medicial condition? what does his descripton of his medical condition tell you about him or his out look on the world ?

Junior defines himself through his medical condition and his "funny" looks. Much of it is self-deprecating humor which Junior uses to deal with the stress of his circumstances. He makes fun of his condition as a way to define the absurdity of his difficult life.
