He teaches English and American Literature at Harry S. Truman Memorial High School (no, it doesn't really exist as that name). Later in the show, he also is given guidance counselor duties. His little buddy, Glendon Farrell, lives next door with his grandmother while his parents are on an extended trip overseas.
