Mr. Sherman Finky is a Social Studies teacher at Hazelnut Middle School.
Mr. Finky can't seem to get out of the era of the "fly" and "fresh". Despite his efforts, his lingo doesn't get him much of anywhere with his class. The only person who has ever tried to cheer him on was Dieter, but he was quickly knocked down by an arsenal of spitballs.
Though Mr. Finky isn't the "hippest" teacher in the school, he doesn't mess around when it comes to giving his class assignments. Among some that he's given are an entire weekend of taking care of a doll ("Doll and Chain"), a weekend of volunteering ("Cocoon Gables"), and an exploration of heritage ("Dances with Ignorance").
