the typical official high school activity culture is personified by preppy muffy b. tepperman (jami gertz) who is the endlessly chipper chairperson of the weemawee pep committee, head of the morals club, chairman of the science fair committee and member of the future nurses of america. muffy has a memorably pompous, oratorical speaking style and begins many sentences with "it behooves me to tell you..." or an elongated "people...". though perhaps even more socially inept ("i’m going to ignore that because, frankly, i don't get it"), muffy's unawareness and/or lack of concern with her failure to fit in with the popular kids is in stark contrast to the motivation of the show's protagonists, and does not stop her from relentless involvement in peppy activities.
