Another type of formal clothes he wears is a green collared shirt, a red and black striped tie, a vest over his green shirt, dark green dress pants, and brown dress shoes.

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 has never been seen before so far in the series.

He also has been seen talking or hanging out with other minor characters in the background including some of the fourth Graders. There is a possibility he is friends with Muffy because the intro of "The Election" portrays him at her side at the presidential inauguration.and in one episode he is seen hanging out with Buster.

 * His name first appeared in the episode, "The Scare-Your-Pants-Off Club!" on a list that Francine was holding, but he was already off-screen, so the name could not be matched to him until the Student-of-the-Month chart in "MacFrensky".
