Relationships
Being in Mr. Ratburn's class, we can assume he has some sort of relationship with the main characters. He is often seen with George and Jenna. He is most of the time seen with Maria and in a few cases talking to her in the background. His family is never seen. There is a possibility he is friends with Muffy because the intro of The Election portrays him at her side at the presidential inauguration.
